Abstract

N -Oxyl-mediated electrooxidation of alcohols was performed in an aqueous silica gel disperse system. The newly devised electrolysis system offers an organic solvent-free and operationally simple procedure for oxidation of alcohols and could be successfully applied to kinetic resolution of sec -alcohol as well as enantioselective oxidation of meso -1,4-diol affording optically active γ-lactone.

Abstract

Tetrakis(dimethylamino)ethylene (TDAE) was found to be a potent organic electron source which could promote alkenylation of several kinds of aldehydes in the presence of a catalytic amount of NiBr 2 and CrCl 3 .
