A novel method has been reported involving the synthesis of z-styryl sulfides by the reaction of phenylacetylene with 2-mercpto benzimidazoles and benzthiazole using NaOH as a base in absolute ethanol. On further oxidation with H2O2, these resulted in the formation of the desired styryl sulfones in good yields with retention of stereochemistry.
