DDQ-mediated regioselective C–S bond formation: efficient access to allylic sulfides

A protocol for the synthesis of allylic sulfides from simple allylic hydrocarbons with thiophenol derivatives via a DDQ-mediated oxidative dehydrogenation strategy is described. This reaction possesses good functional group compatibility, broad substrate scope, and high atom- and step-economy. Moreover, the synthetic utility of this method can be highlighted by its application in the synthesis of versatile organo-sulfur compounds.
