Thiocyanogen chloride reacts with various unsymmetrical alkenes, cycloalkenes, and α- arylalkenes in the presence of a radical inhibitor in acetic acid in the dark at 25° C to yield α- chloro-β-thiocyanates, α-acetoxy-β-thiocyanates, α-hydroxy-β-thiocyanates, vinylic thiocyanates or allylic isothiocyanates in various combinations. The additions to the α- arylalkenes are regiospecific, yielding the Markownikov-orientated products, but the ...
