Metal- and Oxidant-Free Electrochemical Oxidative Desulfurization C–O Coupling of Thiourea-Type Compounds with Alcohols.

An efficient desulfurization C–O coupling reaction of 3,4-dihydropyrimidine-2(1 H)-thiones (including thioureas) with alcohols was developed under electrochemical oxidation conditions. Herein, transition--metal catalysts and additives are not required and the alcohol is both the solvent and the alkoxy donor. [ABSTRACT FROM AUTHOR]
