摘要

A variety of (Z)-1,2-bis(arylthio)-substituted alkenes have been conveniently synthesised in high yields by the stereoselective addition of diaryl disulfides to terminal alkynes catalysed by an MCM-41-supported bidentate phosphine palladium(0) complex. This polymeric palladium catalyst can be recovered and reused many times without any loss of activity.
