Treatment of methyl alkynyl sulfides with low-valent tantalum (TaCl5 and Zn) in 1,2-dimethoxyethane (DME) and benzene produces unisolable tantalum-alkyne complexes, which react with carbonyl compounds at the 2-position of the alkenyl sulfides to give (E)-3-hydroxy-1-propenyl methyl sulfide derivatives in a regio- and stereoselective manner.
