Graphene oxide as a carbocatalyst: the first example of a one-pot sequential dehydration–hydrothiolation of secondary aryl alcohols

Abstract

An efficient and mild one-pot graphene oxide (GO)-catalyzed sequential dehydration–hydrothiolation reaction has been developed for the first time from a mixture of secondary aryl alcohols and thiols. The resulting unsymmetrical thioethers were prepared under metal-free conditions. The catalyst can be reused for five runs with appreciable conversions.
