Regioselective Markovnikov Hydrochalcogenation of Terminal Alkynes with Indium(III) Benzenechalcogenolates

Abstract Indium(III) benzenechalcogenolates (chalcogen = sulfur and selenium) promote the rigorous Markovnikov hydrochalcogenation of terminal alkynes. The generality and limitations of the reaction with aminoalkynes leading to allylic amines bearing vinylic chalcogenide substituents are discussed.
