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

Abstract

An efficient desulfurization C–O coupling reaction of 3,4-dihydropyrimidine-2(1H)-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.

Key words

electrochemical oxidation - alkoxylation - alcohols - thioureas - desulfurization
