The product of addition of benzenesulphenyl chlorides to phenylacetylene is solvent-dependent: in ethyl acetate anti-Markownikoff (A) orientation predominated, whereas in acetic acid Markownikoff addition (M) was favoured. In chloroform and acetonitrile both adducts were formed, in similar amounts. In contrast, addition to but-1-yne yielded the A-adduct in every solvent.
