The reactivity of ketyl and alkyl radicals in reactions with carbonyl compounds

Denisov

, p. 2110 - 2116 (1998)

A parabolic model of bimolecular radical reactions was used for analysis of the hydrogen transfer reactions of ketyl radicals: >C+OH + R1COR2 → >C=O + R1R2C+OH. The parameters describing the reactivity of the reagents were calculated from the experimental data. The parameters that characterize the reactions of ketyl and alkyl radicals as hydrogen donors with olefins and with carbonyl compounds were obtained: >C+OH + R1CH=CH2 → >C=O + R1C+ HCH3; >R1CH=CH2 + R2C+HCH2R3 → R2C+HCH3 + R2CH=CHR3. These parameters were used to calculate the activation energies of these transformations. The kinetic parameters of reactions of hydrogen abstraction by free radicals and molecules (aldehydes, ketones, and quinones) from the C-H and O-H bonds were compared.

An ionic compound containing Ru(III)-complex cation and phosphotungstate anion as the efficient and recyclable catalyst for clean aerobic oxidation of alcohols

Wang, Sa-Sa,Zhang, Jing,Zhou, Cheng-Liang,Vo-Thanh, Giang,Liu, Ye

, p. 152 - 154 (2012)

A novel ionic compound (3, [RuCl4(L)2] 3PW12O40) containing the Ru(III)-complex cation and α-Keggin-type phosphotungstate anion was synthesized and proven to be the efficient catalyst for aerobic oxidations of alcohols free of base and nitroxyl radical. Specially, 3 could be reused at least five runs without obvious activity loss. The stability of 3 was dramatically improved due to the incorporation of [PW12O40]3 - as the counter-anions, leading to its available recyclability.

Thermal Ring-Splitting Reactions of Diarylcyclobutanes: Significance of Steric Effects on Orbital Interactions in Transition States and Biradical Intermediates

Yasuda, Masahide,Yoshida, Kouhei,Shima, Kensuke,Pac, Chyongjin,Yanagida, Shozo

, p. 1943 - 1950 (1989)

Regiochemistry and rectivities in the thermal ring-splitting reactions of diarylcyclobutanes (1-5) have been studied and shown to depend on the stable conformations and rotational mobilities of the aryl substituents.The reactions of 1 and 2 result in a regiospecific symmetric cleavage to give indene or styrene along with significant isomerization of 2 to 3.In the cases of 3-5 both the symmetric and unsymmetric cleavages competitively occur with decreasing symmetric-to-unsymmetric ratios with an increase in methyl substitution.The olefin products from 4 are mixtures of cis- and trans-2-butene, cis- and trans-β-methylstyrene, and trans-stilbene.Thermochemical analyses combined with product analyses indicate that the symetric cleavage of 1 and the unsymmetric cleavage of 3 proceed with a concerted mechanism, whereas 1,4-biradicals are involved in the other reactions.Structure-reactivity relationships of the present reactions are discussed in terms of mixing of the ?* character in a bonding MO by specific ?-?* interactions, depending on the conformational situations of the aryl groups and in terms of the steric effects which destabilize 1,4-biradicals as well as transition states of the biradical fragmentation to the olefins.

Here we reported the synthesis of Al sites with ultra-high dispersion on anatase by an atomic layer deposition (ALD) method (ALD-Al/TiO2), which exhibits Br?nsted acidity and satisfactory activity in the dehydration of alcohols, a key step in the deoxygenation of biomass. More importantly, the ALD-Al/TiO2 catalyst has good stability, which is sintering-resistant and gives constant catalytic performances after treatments at high temperature.

Readily recyclable catalysts of zeolite nanoparticles linked with polymer chains

Okamoto, Masaki,Watanabe, Satoshi,Nitta, Junya

, p. 55 - 60 (2013)

Aggregates of zeolite nanoparticles were linked together with polypropylene oxide or polydimethylsiloxane polymer chains, and were used as catalysts for liquid-phase reactions. The polymer-linked catalysts showed high catalytic activity in esterification of acetic acid with 1-propanol and hydrolysis of ethyl acetate, and were readily separated from reaction mixtures by decantation. Moreover, the linkage with the polymer chains enhanced shape selectivity in esterification of acetic acid with cyclohexanol and dehydration of 1-phenylethanol because of passivating the external acid sites of the zeolite with the polymer.

β-Cyclodextrin as a Molecular Reaction Vessel: Reactions of Included Phenylmethyldiazirine

Abelt, Christopher J.,Pleier, Jennifer M.

, p. 2159 - 2162 (1988)

Phenylmethyldiazirine forms a stable, solid complex with β-cyclodextrin.The diazirine was decomposed by pyrolysis or irradiation of the complex, and the reaction products were analyzed.The major volatile products consist of the isomeric 1,2-diphenyl-1-methylcyclopropanes.Under photolytic conditions a significant amount of styrene also is formed.The selectivity for trans isomer formation is 10 times greater from the CD complex than from the neat state.Carbene insertion products with β-cyclodextrin are formed under both reaction conditions.The product distributions are explained by cage and shape-selective effects exerted by β-cyclodextrin.

CARBONYLATIVE CROSS-COUPLING REACTION OF ARYL IODIDES WITH ALKYLALUMINUMS BY PALLADIUM COMPLEX CATALYSIS

Wakita, Yoshiaki,Yasunaga, Tomoyuki,Kojima, Masaharu

, p. 261 - 268 (1985)

Secondary and/or tertiary alcohols and unsymmetrical ketones have been obtained in moderate to good yields by palladium-catalyzed (5 molpercent) carbonylative coupling of aryl iodides with alkylaluminum compounds under very mild conditions (20-50 deg C, 1 atm of carbon monoxide).The type of th reaction product depended on the aluminum reagent employed.While the selective formation of secondary alcohols was observed in the reaction with i-Bu3Al, the use of Et3Al led to a mixture of a ketone and two alcoholic products.With Et2AlCl predominantly unsymmetrical ketones were produced.In all cases, formation of directly cross-coupled products was not observed.DME and benzene can be used as solvents, but THF is unsuitable.Nickel catalysts were found to be ineffective for this reaction.

Mechanistic Studies of Single-Step Styrene Production Catalyzed by Rh Complexes with Diimine Ligands: An Evaluation of the Role of Ligands and Induction Period

Zhu, Weihao,Luo, Zhongwen,Chen, Junqi,Liu, Chang,Yang, Lu,Dickie, Diane A.,Liu, Naiming,Zhang, Sen,Davis, Robert J.,Gunnoe, T. Brent

, p. 7457 - 7475 (2019)

Studies of catalytic benzene alkenylation using different diimine ligated Rh(I) acetate complexes and Cu(OAc)2 as the oxidant revealed statistically identical results in terms of activity and product selectivity. Under ethylene pressure, two representative diimine ligated rhodium(I) acetate complexes were demonstrated to exchange the diimine ligand with ethylene rapidly to form [Rh(μ-OAc)(??2-C2H4)2]2 and free diimine. Thus, it was concluded that diimine ligands are not likely coordinated to the active Rh catalysts under catalytic conditions. At 150 °C under catalytic conditions using commercial Cu(OAc)2 as the oxidant, [Rh(μ-OAc)(??2-C2H4)2]2 undergoes rapid decomposition to form catalytically inactive and insoluble Rh species, followed by gradual dissolution of the insoluble Rh to form the soluble Rh, which is active for styrene production. Thus, the observed induction period under some conditions is likely due to the formation of insoluble Rh (rapid), followed by redissolution of the Rh (slow). The Rh decomposition process can be suppressed and the catalytically active Rh species maintained by using soluble Cu(II) oxidants or Cu(OAc)2 that has been preheated. In such cases, an induction period is not observed.

Selective Semi-Hydrogenation of Terminal Alkynes Promoted by Bimetallic Cu-Pd Nanoparticles

Buxaderas, Eduardo,Volpe, María Alicia,Radivoy, Gabriel

, p. 1466 - 1472 (2019)

The selective semi-hydrogenation of terminal alkynes was efficiently performed, under mild reaction conditions (H 2 balloon, 110 °C), promoted by a bimetallic nanocatalyst composed of copper and palladium nanoparticles (5:1 weight ratio) supported on mesostructured silica (MCM-48). The Cu-PdNPS@MCM-48 catalyst, which demonstrated to be highly chemoselective towards the alkyne functionality, is readily prepared from commercial materials and can be recovered and reused after thermal treatment followed by reduction under H 2 atmosphere.

Photoredox Catalyzed Sulfonylation of Multisubstituted Allenes with Ru(bpy)3Cl2 or Rhodamine B

Chen, Jingyun,Chen, Shufang,Jiang, Jun,Lu, Qianqian,Shi, Liyang,Xu, Zekun,Yimei, Zhao

supporting information, (2021/11/09)

A highly regio- and stereoselective sulfonylation of allenes was developed that provided direct access to α, β-substituted unsaturated sulfone. By means of visible-light photoredox catalysis, the free radicals produced by p-toluenesulfonic acid reacted with multisubstituted allenes to obtain Markovnikov-type vinyl sulfones with Ru(bpy)3Cl2 or Rhodamine B as photocatalyst. The yield of this reaction could reach up to 91%. A series of unsaturated sulfones would be used for further transformation to some valuable compounds.
