A simple, stereoselective and efficient method for the hydrothiolation of terminal alkynes with diaryl disulfides and diphenyl diselenide has been developed. In the presence of CuI, rongalite, and Cs2CO3, a variety of disulfides underwent the reaction of terminal alkynes stereoselectively to afford the corresponding (Z)-1-alkenyl sulfides in moderate to excellent yields. It is noteworthy that hydroselenations of 1,2-diphenyldiselane with alkynes are also conducted smoothly to afford (Z)-1-alkenyl selenides in good yields under the standard conditions.

Very mild conditions have been found for the efficient regioselective addition of phenylthiol to ethynyl carbinols.A biphasic aqueous acid hydrolysis then leads to αβ-unsaturated aldehydes.The Meyer-Schuster rearrangement is thus brought about in two steps.
