Ni-Catalyzed Reductive Fluoroalkylthiolation of Alkynes toward Fluoroalkylated Vinylthioethers

A Ni-catalyzed protocol for the regioselective and stereoselective three-component fluoroalkylthiolation of alkynes with fluoroalkyl halides and thiosulfonates is presented. This reductive difunctionalization provides an efficient strategy for the rapid construction of fluoroalkyl-incorporated vinylthioethers under mild conditions in moderate to good yields.
