摘要

The electrocarboxylation of benzyl halides to the corresponding carboxylic acids through homogeneous charge-transfer catalysis was investigat-ed both theoretically and experimental-ly to determine the influence of the op-erative parameters on the yield of the process and on the catalyst consump-tion.Theoretical considerations,based on fast kinetics of redox catalysis,were confirmed by the electrocarboxylation of 1-phenyl-1-chloroethane catalyzed by 1,3-benzenedicarboxylic acid di-methyl ester performed at a carbon cathode under different operative con-ditions.We obtained high yields of the target carboxylic acid and experienced a low catalyst consumption by operat-ing with optimized [RX]~(bulk)/[CO_2]~(bulk) and [RX]~(bulk)/[catalyst] ratios.
