Cobalt-Catalyzed Selective Functionalization of Aniline Derivatives with Hexafluoroisopropanol

Abstract

A cobalt-catalyzed site-selective functionalization of aniline derivatives with hexafluoroisopropanol, which enables the synthesis of a wide array of fluoroalkylated anilines, a class of highly valuable building blocks for further preparation of fluorinated functional products, is reported. The developed transformation proceeds with operational simplicity, use of earth-abundant metal catalyst, broad substrate scope, good functional group tolerance, and mild reaction conditions.
