Thiocyanogen does not react with simple alkynes under heterolytic conditions in benzene at 20-25°. Under homolytic conditions, addition occurs readily giving mixtures of E- and Z- dithiocyanatoalkenes with high E:Z ratios; prolonged treatment with excess reagent also leads to mixtures of the dithiocyanatoalkenes but usually with lower E:Z ratios. A radical-chain mechanism, involving preferential anti-addition
