Abstract

Abstract Vinyl sulfide formation with good yield and high regio-and stereoselectivities from thiols and acetylenes under transition-metal-free conditions is described. Potassium phosphate was used as an effective additive to enhance the reaction yield and selectivity. Z- Vinyl sulfides were predominately formed in the presence of potassium phosphate, whereas E-vinyl sulfides were formed under solvent-and base-free conditions.
