Abstract

Indirect electroreductions of 4-methyl-4-trichloromethyl-p-quinone-(1)-arylimines using a sacrificial sulfur-graphite electrode (S-C electrode) caused the elimination of a trichloromethyl group to give the corresponding N-tolylarylamines, whose yields increased largely with an increase in temperature and by the addition of benzoic acid as a proton donor. Similarly, diimines with two trichloromethyl groups underwent the elimination of two trichloromethyl groups. The above indirect electroreduction using the S-C electrode was undertaken at the low cathodic overpotential, and gave high product yields compared with the direct electroreduction.
