ortho-Cyanomethylation of aryl fluoroalkyl sulfoxides via a sulfonium–Claisen rearrangement

Abstract

We hereby report the ortho-cyanomethylation of aryl fluoroalkyl sulfoxides with acetonitrile through sulfonium-Claisen type rearrangement. The reaction enables the incorporation of two valuable functional groups, namely the cyanomethyl group and...
