acetic, benzoic, and hippuric acids to propadienyl, prop-1-ynyl, and prop-2-ynyl p-tolyl sulphones and to ethynyl phenyl ketone occur readily under mild conditions. The products are 1-(aryl-sulphonylmethyl)vinyl or β-benzoylvinyl esters of the acids and as such are very reactive towards nucleophiles in acylation reactions.
