Organocatalyzed anodic oxidation of aldehydes
Witryna1 lip 2011 · The enantioselective organocatalyzed alkylation at the α-C–H bond of aldehydes with xanthene was achieved by anodic oxidation in the presence of chiral cyclic amines. The components were electrolyzed current controlled in 0.1 M TBAClO 4 in DCM at platinum electrodes. Witryna20 gru 2024 · The organocatalyzed aerobic oxidation of aldehydes to acids was reproduced from the original report. In- and ex-situ analysis of the reaction mixture as the function of time reveals that, unlike the claim in the publication, the aerobic oxidation of aromatic and aliphatic aldehydes leads predominantly to the formation of peracids. …

Changming Qin,, … Witryna13 paź 2009 · Electrochemical oxidation was performed during the organocatalyzed α-oxyamination of aldehydes by using a one-compartment electrolytic cell under galvanostatic conditions. In the presence of substoichiometric amounts of sec-amines, the desired coupling products were formed in good yield.
Witryna22 gru 2009 · An anodic oxidation/organocatalytic α-arylation of aldehydes using substituted electron-rich aromatic compounds has been developed. The method gives access to meta-substituted anilines and dihydrobenzofurans in good yields and excellent enantioselectivity (see scheme; Pg=protecting group).
