Benzeneselenenyl p-toluenesulfonate: Formation and electrophilic addition to acetylenes

The title compound 1 was produced in situ from PhSeCl and AgOSO2Ar (Ar = p-tolyl), and underwent electrophilic addition of acetylenes to afford adducts 2. The same products were unexpectedly formed from the reaction of ArSO3H and AIBN, or from the pyrolysis of ArS(O)SO2Ar, in the presence of acetylenes and PhSeSePh.
