Effective oxidation of alcohols with H5IO6 catalyzed by nickel(II) schiff base complexes

Ramakrishna, Dileep,Bhat, Badekai Ramachandra

, p. 516 - 520 (2010)

Nickel(II)-Schiff base-triphenylphosphine complexes catalyze oxidation of alcohols to carbonyls in presence of minimum amount of periodic acid. The catalytic oxidation was developed in mild conditions and showed good yields. The effects of temperature, time, and concentrations of catalyst and co-oxidant were studied. Higher catalytic activity has been observed for NiL1 compared to the other complexes.Copyright Taylor & Francis Group, LLC.

Effect of CTAB micelle on the oxidation of L-Leucine by N-Bromophthalimide: A kinetic study

Katre, Yokraj,Goyal, Namita,Kumar Singh, Ajaya

, p. 107 - 124 (2011)

The effect of cationic surfactant cetyltrimethylammonium bromide (CTAB) on the oxidation of L-leucine by N-bromophthalimide (NBP) has been studied at 308 K. The reaction exhibits first order dependence on NBP and L-leucine and negative and fractional order dependence on HClO4. The effects of KCl, KBr, phthalimide and mercuric acetate have also been studied and summarized. The rate of reaction increased with an increase in dielectric constant of the medium. CTAB strongly catalyzes the reaction and typical k obs and CTAB profile was observed, i.e., with a progressive increase in CTAB, the reaction rate increased and after achieving a peak kobs decreased at higher concentrations of CTAB. The results are treated quantitatively in terms of "Piszkiewicz" and "Raghvan and Srinivasan's" models. The various activation parameters in presence and absence of CTAB have been also evaluated. A suitable mechanism consistent with the experimental findings has been proposed. The rate constant in micellar phase kM, cooperativity index (n), binding constant (K1 and K2) have been computed. by Oldenbourg Wissenschaftsverlag, Mu?nchen.

Mixed anionic-nonionic micelle catalysed oxidation of aliphatic alcohol in aqueous medium

Acharjee, Animesh,Ali, Md. Ansar,Chowdhury, Suman,Rakshit, Atanu,Saha, Bidyut,Singh, Bula

, (2020)

Oxidation of isoamyl alcohol was carried out under pseudo 1st order reaction condition in aqueous medium by chromic acid. In addition to single micelle, mixed anionic-nonionic micelle (SDS-TX 100) was found to be effective catalyst. Promoters in presence of micelle catalyst showed almost million fold rate acceleration. The product was confirmed by IR and NMR study. UV and NMR analysis were carried out to establish the formation of mixed micelle. Formation of active oxidant was confirmed by fluorescence measurement. Interactions between surfactant and substrate were analysed by NMR spectra. In addition to SDS catalysed Bpy promoted reaction combination of mixed micelle with Bpy promoter was found to show higher rate of oxidation. For single micelle catalysed path the observed rate constants follow the order kobs (SDS) > kobs (TX 100) and kobs (Phen) > kobs (Bpy) > kobs (PA) was observed for promoted reactions. In SDS micelle and mixed micelle kobs (Bpy) > kobs (Phen) > kobs (PA) was observed while in TX 100 micelle kobs (Phen) > kobs (Bpy) > kobs (PA) was found.

Isobutene hydroformylation in catalytic systems based on rhodium compounds and polyelectrolytes

Sharikova,Kolesnichenko,Markova,Slivinskii

, p. 701 - 703 (1999)

The catalytic properties of water-soluble systems based on rhodium complexes and polyelectrolytes in isobutene hydroformylation were studied. All of the catalytic systems exhibited an unexpectedly high activity under the conditions where homogeneous hydroformylation virtually did not occur in the presence of conventional rhodium catalysts. A stable catalytic system based on acacRh(CO)2 - PEG complex was proposed, allowing isobutene hydroformylation to be performed with a high activity under mild conditions.

Hydroformylation of olefins in the presence of rhodium carbonyl catalysts immobilized on polymeric pyrrolidinopyridines

Terekhova,Kolesnichenko,Alieva,Markova,Trukhmanova,Slivinsky,Plate

, p. 1583 - 1585 (1996)

The hydroformylation of olefins in the presence of catalytic systems based on RhCl3 and polymeric pyrrolidinopyridines was studied. It was shown that the catalytic system has high activity in the hydroformylation of isobutylene under conditions when the activity of conventional homogeneous catalysts is low. The polymeric catalysts are also thermostable. The effect of solvents on the catalytic properties of the system was studied.

Purification and characterization of isoamyl alcohol oxidase ("Mureka"-forming enzyme)

Yamashita, Nobuo,Motoyoshi, Toru,Nishimura, Akira

, p. 1216 - 1222 (1999)

Isoamyl alcohol oxidase (IAAOD) was purified to apparent homogeneity on SDS-PAGE from ultrafiltration (UF) concentrated sake. IAAOD was a glycoprotein, a monomeric protein with an apparent molecular mass of 73 and 87 kDa, by SDS-PAGE and gel filtration on HPLC, respectively. IAAOD showed high substrate specificity toward C5 branched-chain alkyl alcohol (isoamyl alcohol), and no activity toward shorter (C1-C4) or longer (C7-C10) alkyl alcohols tested. IAAOD was stable between pH 3.0-6.0 at 25°C. The optimum pH was 4.5 at 35°C. Heavy metal ions, p-chloromercuribenzoate (PCMB), hydrazine, and hydroxylamine strongly inhibited the enzyme activity, and an anti-oxidant like L-ascorbate did also. Isovaleraldehyde was produced markedly in pasteurized sake by adding purified IAAOD, therefore, we concluded that it was the enzyme that causes formation of mureka, an off-flavor of sake, the main component of which is isovaleraldehyde.

Aerobic oxidation of alcohols with ruthenium catalysts in ionic liquids

Wolfson, Adi,Wuyts, Stijn,De Vos, Dirk E.,Vankelecom, Ivo F.J.,Jacobs, Pierre A.

The aerobic oxidations of aliphatic and aromatic alcohols into the corresponding aldehydes and ketones have been efficiently performed with several ruthenium catalysts in various ammonium salts under low oxygen pressure and without any co-catalyst.

Mechanistic study of [RuCl3(H2O)2OH]- catalyzed oxidation of L-leucine by acidic N-bromophthalimide

Jain, Bhawana,Singh, Ajaya Kumar,Negi, Reena

, p. 1717 - 1728 (2015)

Kinetic studies in homogenous Ru(III) catalyzed oxidation of L-leucine (Leu), by N-bromophthalimide (NBP) in the presence of perchloric acid have been made at 303 K using mercuric acetate as Br- ion scavenger. The reaction follows first-order kinetics with respect to [NBP]. In the lower concentration range of Leu and Ru(III) chloride, the reaction follows first-order kinetics but tends to zero at higher concentration. A positive effect of [Cl-] was observed in the oxidation of Leu. An increase in the rate of reaction with the decrease in dielectric constant of the medium was observed while negative effect was observed for [H+]. The rate of oxidation is unaffected by the change in [phthalimide (NHP)]. Rate of reaction decreased with increase in ionic strength of the medium. The main oxidation products of the reactions were identified as aldehyde, ammonia and CO2 for the oxidation of Leu. From the effect of temperature (298-318 K) on the reaction rate, various activation parameters have been calculated and on the basis of these parameters, a suitable explanation for the reaction mechanism has been given.

Kinetic studies of transition metal ion catalyzed oxidation of some fragrance alcohols

Prabhu,Parbat,Tandel

, p. 6669 - 6673 (2014)

The controlled oxidation of the aliphatic alcohols 2-propanol, 2-butanol and 3-methyl-1-butanol to the corresponding carbonyl compounds has been carried out using Ce (IV) in acidic medium in the absence and presence of transition metal ions of the first series. The aliphatic alcohols are widely used as diluents in the perfumery industry. The oxidation reaction was monitored under pseudo unimolecular conditions with respect to [Ce (IV)] in the temperature range 303-318 K. Aliquots of the reaction were withdrawn at regular time intervals, quenched using ice and the unreacted oxidant was estimated titrimetrically using standard ferrous ammonium sulphate with ferroin as indicator. The pseudo first order rate constants were determined from the linear plots of log (a-x) versus time. It was observed that the rate increases with alcohol concentration but decreases with Ce(IV) concentration. This has been attributed to the formation of unreactive dimeric [Ce(IV)]2at higher concentration of Ce(IV). Potassium sulfate was used to study the effect of ionic strength on the oxidation rate. The thermodynamic activation parameters were determined from the effect of temperature on the oxidation rate. The Ru(VIII), Os(VIII) and Cr(VI) ions have been exhaustively used to catalyse a variety of organic reactions. In the present study, relatively low-cost metal ions of the first transition series have been used as effective catalysts for the oxidation of the fragrance alcohols under study. The reaction mechanism suggested for the oxidation process involves intermediates with hypervalent ions i.e., M(III). The catalytic efficiency of the metal ions is based on the stability of the complexes formed as reaction intermediates which in turn depends on the charge density of the metal ions involved. We have observed some discrepancies as the experimentally determined sequence of catalytic efficiency of metal ions does not follow the theoretically expected sequence. Suitable reaction mechanisms have been suggested for the oxidation of the alcohols in the absence and presence of transition metal ions. In the absence of metal ions, the oxidation rates of aliphatic alcohols the sequence: 2-propanol > 2-butanol > 3-methyl-1-butanol. The relative rates of oxidation of alcohols have been discussed and explained on the basis of structures, steric factors and isomeric characteristics of the perfumery alcohols under study.

Dual utility of a single diphosphine-ruthenium complex: A precursor for new complexes and, a pre-catalyst for transfer-hydrogenation and Oppenauer oxidation

Mukherjee, Aparajita,Bhattacharya, Samaresh

, p. 15617 - 15631 (2021/05/19)

The diphosphine-ruthenium complex, [Ru(dppbz)(CO)2Cl2] (dppbz = 1,2-bis(diphenylphosphino)benzene), where the two carbonyls are mutually cis and the two chlorides are trans, has been found to serve as an efficient precursor for the synthesis of new complexes. In [Ru(dppbz)(CO)2Cl2] one of the two carbonyls undergoes facile displacement by neutral monodentate ligands (L) to afford complexes of the type [Ru(dppbz)(CO)(L)Cl2] (L = acetonitrile, 4-picoline and dimethyl sulfoxide). Both the carbonyls in [Ru(dppbz)(CO)2Cl2] are displaced on reaction with another equivalent of dppbz to afford [Ru(dppbz)2Cl2]. The two carbonyls and the two chlorides in [Ru(dppbz)(CO)2Cl2] could be displaced together by chelating mono-anionic bidentate ligands, viz. anions derived from 8-hydroxyquinoline (Hq) and 2-picolinic acid (Hpic) via loss of a proton, to afford the mixed-tris complexes [Ru(dppbz)(q)2] and [Ru(dppbz)(pic)2], respectively. The molecular structures of four selected complexes, viz. [Ru(dppbz)(CO)(dmso)Cl2], [Ru(dppbz)2Cl2], [Ru(dppbz)(q)2] and [Ru(dppbz)(pic)2], have been determined by X-ray crystallography. In dichloromethane solution, all the complexes show intense absorptions in the visible and ultraviolet regions. Cyclic voltammetry on the complexes shows redox responses within 0.71 to -1.24 V vs. SCE. [Ru(dppbz)(CO)2Cl2] has been found to serve as an excellent pre-catalyst for catalytic transfer-hydrogenation and Oppenauer oxidation.

Chemoselective hydrogenation of α,β-unsaturated aldehydes over Rh nanoclusters confined in a metal-organic framework

Liu, Qinglin,Li, Yinle,Fan, Yanan,Su, Cheng-Yong,Li, Guangqin

, p. 11442 - 11447 (2020/06/29)

Selective hydrogenation of α,β-unsaturated aldehydes to achieve high selectivity towards a desirable product is still a great challenge mainly because of the complex conjugate system. Herein, Rh nanoclusters encapsulated in MIL-101 (Cr), synthesized by the double solvent method, are able to selectively hydrogenate C-C of cinnamaldehyde, an α,β-unsaturated aldehyde and achieve over 98percent selectivity with a conversion of 98percent to a saturated aldehyde under mild conditions. Fourier transform infrared spectroscopy confirms that MIL-101 acts as an aldehyde protector to suppress the reactivity of C-O, and the X-ray photoelectron spectroscopy (XPS) data indicate that the electropositive Rh, owing to the electron transfer from Rh to MIL-101, preferentially absorbs C-C rather than C-O leading to -improvement of the selectivity towards saturated aldehydes. In addition, Rh@MIL-101 can also efficiently catalyse hydrodefluorination of aryl fluorides with good stability. This work provides a basic strategy to develop other selective heterogeneous catalystsviastructural modulation for synergetic catalysis.

Solvent-free, microwave assisted oxidation of alcohols with 4-hydroxypyridinium chlorochromate functionalized silica gel

AHMADI, Sayed Ali,GHALEHBANDI, Shermineh Sadat,GHAZANFARI, Dadkhoda,SHEIKHHOSSEINI, Enayatollah

, p. 283 - 289 (2020/10/06)

4-Hydroxypyridinium chlorochromate functionalized silica gel was found to be an efficient and reusable oxidant for the very fast oxidation of primary and secondary alcohols to the corresponding carbonyl compounds under solventfree conditions and microwave irradiation in excellent yields.

Selective Oxidation of Alcohols to Carbonyl Compounds over Small Size Colloidal Ru Nanoparticles

Zhao, JingPeng,Hernández, Willinton Y.,Zhou, WenJuan,Yang, Yong,Vovk, Evgeny I.,Capron, Mickael,Ordomsky, Vitaly

, p. 238 - 247 (2019/11/14)

The selective oxidation of alcohols to corresponding aldehydes is one of the most challenging problems in modern chemistry due to over-oxidation of these products further into corresponding acids and esters. Herein, we report an efficient and eco-friendly method for selective oxidation of aliphatic, unsaturated and aromatic alcohols to aldehydes (>90 %) using small size (2 nm) non-supported colloidal Ru nanoparticles. The selectivity rapidly decreases with increase of the size of nanoparticles (from 2 to 10 nm) or after their deposition over support. X-ray photoelectron spectroscopy suggests that this catalytic performance can be attributed to high content Ru?O species on the surface of small size Ru nanoparticles, which undergo reduction with formation of water and aldehyde and easy oxidation cycles during the reaction according to the Mars-van Krevelen mechanism. The presence of surface oxide layer over small size Ru nanoparticles suppresses over-oxidation of aldehydes to acids.
