Dowex polymer-mediated protection of carbonyl groups
Niknam, Khodabakhsh,Kiasat, Ali Reza,Karimi, Sadegh
, p. 2231 - 2236 (2005)
Dowex (strongly acidic cationic exchange resin) polymer is employed as solid acid catalyst for the clean and less hazardous protection of carbonyl compounds as phenylhydrazones and 2,4-dintrophenylhydrazones in ethanol under reflux conditions. The reactions proceed very smoothly and the yields of the derivatives are excellent. Copyright Taylor & Francis, Inc.
Revisiting the reaction of hydroxyl radicals with vicinal diols in water
Jiang, Dong,Barata-Vallejo, Sebastian,Golding, Bernard T.,Ferreri, Carla,Chatgilialoglu, Chryssostomos
, p. 1102 - 1107 (2012)
The carbonyl products of the reactions of hydroxyl radicals with three vicinal diols (ethane-1,2-diol, propane-1,2-diol and butane-2,3-diol) have been identified and quantified. Hydroxyl radicals were produced by γ-radiolysis of N2O-saturated aqueous solutions. The reactions result in the formation of alkoxyl radicals (～15%) followed by β-fragmentation, and α-hydroxyl alkyl radicals that undergo H2O elimination. The latter process is part of a radical chain reaction at higher diol concentrations.
Analysis of carbonyl compounds in sea buckthorn for the evaluation of triglyceride oxidation, by enzymatic hydrolysis and derivatisation methodology
Mathew, Sindhu,Grey, Carl,Rumpunen, Kimmo,Adlercreutz, Patrick
, p. 1399 - 1405 (2011)
Carbonyl compounds formed in sea buckthorn berry (Hippophae rhamnoides) and oil samples as a result of lipid oxidation were determined by enzymatic hydrolysis followed by derivatisation with 2,4-dinitrophenylhydrazine and analysed by LC-UV and electrospra

Effect of CHAPS and CPC micelles on Ir(III) catalyzed Ce(IV) oxidation of aliphatic alcohols at room temperature and pressure
Ghosh, Aniruddha,Saha, Rumpa,Saha, Bidyut
, p. 223 - 237 (2014)
Kinetics of cerium(IV) oxidation of aliphatic alcohols: ethanol, propanol, propan-2-ol, 1-butanol and 2-butanol were studied at 30 °C in the presence and absence of surfactants in acidic medium. The reaction was studied under pseudo-first-order conditions
Synthesis of N-Sulfonylformamidines by tert-butyl Hydroperoxide–Promoted, metal-free, direct oxidative dehydrogenation of aliphatic amines

A direct and convenient metal-free method to prepare sulfonyl amidines in the presence of aqueous tert-butyl hydroperoxide (T-HYDRO) has been developed. Different tertiary and secondary amines were tested for compatibility with the oxidative conditions and could be coupled with sulfonyl azides to form the corresponding amidines in moderate to good yields.
Selective reduction of esters to aldehydes under the catalysis of well-defined NHC-iron complexes
Li, Haoquan,Misal Castro, Luis C.,Zheng, Jianxia,Roisnel, Thierry,Dorcet, Vincent,Sortais, Jean-Baptiste,Darcel, Christophe
supporting information, p. 8045 - 8049 (2013/08/23)
On a direct course to the aldehyde: Hydrosilylation catalyzed by a well-defined N-heterocyclic-carbene-iron complex under UV irradiation enabled the selective reduction of esters to aldehydes (see scheme; Bn=benzyl, Mes=mesityl). The low catalyst loading and very mild reaction conditions make this chemoselective transformation a promising alternative to the reduction of esters with diisobutylaluminum hydride. Copyright
