Trifluoromethyl‐ and Fluoroalkylselenolations of Alkynyl Copper(I) Compounds

Abstract

The successful perfluoroalkylselenolation of alkynyl copper(I) compounds is described herein. The reaction occurs under oxidant free conditions at room temperature. This convenient one-pot procedure is based on the in situ generation of trifluoromethylselenyl chlorides. The developed system shows high functional group tolerance and also promotes the employment of fluoroalkyl derivatives.
