Abstract

The scope and limitations of triphenylsilanethiol (1) a solid hydrogen sulfide equivalent, were investigated in free radical reactions to terminal alkynes. The triphenylsilylthioenol ether intermediate thus obtained was deprotected with Cs₂CO₃ in the presence of various electrophiles to yield mixtures of E and Z vinyl sulfides. The ratio of E and Z isomers could be controlled by varying the concentration of the starting alkynes.
