Abstract In the presence of a catalytic amount of cesiumhydroxide under a nitrogen atmosphere, terminal alkynes reacted with diaryl disulfides at room temperature in dimethylformamide to give almost exclusively (Z)-1,2-diarylthio-1-alkene in good yields, but under an air atmosphere, the reaction gave a mixture of alkynylsulfide and (Z)-1,2-diarylthio-1-alkene.
