A mechanism of the formation of an aldehyde in the reaction between formic and carboxylic acid has been proposed. It is assumed that a mixed formic-carboxylic anhydride is formed with its subsequent decarboxylation to an aldehyde. On the basis of XRD measurements of freshly prepared manganese ...
Selective reduction of carboxylic acid derivatives by catalytic hydrosilylation. In the last decade, an increasing number of useful catalytic reductions of carboxylic acid derivatives with hydrosilanes have been developed. Notably, the ...

To gain a deeper insight into the protonation mechanism by Tyr169 and Tyr69, DFT calculations were performed using wt-YqjM and the mutant I69Y/Y169F (each containing only one of the above proton transfer sites) as model enzymes. The stationary point energies were obtained according to a ...

The oxidation of aldehydes can take place in an alkaline medium or acid medium. If it is an alkaline medium, the product is the corresponding salt. If the oxidation occurs in an acid medium, the corresponding carboxylic acid is the product. The reaction mechanism takes place with the nucleophi...
Kinetics and mechanism of the glutathione-dependent reduction of dehydromethionine 来自 Elsevier 喜欢 0 阅读量: 13 作者: Paul,R.,Young,and,Anita,V.,Briedis 摘要: Dehydromethionine (S-methylisothiazolidine-3-carboxylic acid) is reduced by glutathione (aqueous solution, 25°C) to give methionine ...
The conversion of methanol over zeolites offers a sustainable alternative for fuels and chemicals production. However, a complete understanding of the competing reaction pathways, particularly those leading to C-C bond formation, remains elusive. This wo
hydroxy carboxylic acidsThe reaction of Np(VI) with organic acid anions in solutions containing lithium salts of tartaric, malic, 伪-aminoglutaric, and trihydroxyglutaric acids was studied. Changes in the solution spectra show that Np(VI) forms complexes with organic acid anions, which is followed...
