Abstract

3-mercapto-2-butanone undergoes a smooth reaction with electron-deficient symmetric and asymmetric acetylenes in the presence of catalytic amount of triphenylphosphine under neutral conditions to produce S-functionalized vinyl sulfides (Z/E isomers) in moderately high yields.

Keywords: Triphenylphosphine, alkyl propiolate, organophosphorus compounds, vinyl sulfides
