Nickel‐Catalyzed Decarboxylative Difluoroalkylation of α,β‐Unsaturated Carboxylic Acids

Abstract

The first example of nickel-catalyzed decarboxylative fluoroalkylation of α,β-unsaturated carboxylic acids has been developed with commonly available fluoroalkyl halides. This novel transformation has demonstrated broad substrate scope, excellent functional-group tolerance, mild reaction conditions, and excellent stereoselectivity. Mechanistic investigations indicate that a fluoroalkyl radical is involved in the catalytic cycle.
