Stereo- and Regioselective Synthesis of (Z)-β-Arylseleno-α,β-Unsaturated Ketones via Selenocarbonylation Addition of Arylselenoesters to Alkynes Catalyzed by Copper(I).

Abstract Selenocarbonylation addition reaction of selenoesters to nonactived terminal alkynes under the catalysis of CuX produces (Z)-β-arylseleno-α,β-unsaturated ketones in high selectivity and high yields. The mechanism of this reaction is also discussed.
