A simple and practical method for the synthesis of alkenyl dithiocyanates and alkenyl diselenocyanates has been developed via stereoselective difunctionalization of alkynes with NaSCN or KSeCN at room temperature. Through this methodology, a series of alkenyl dithiocyanates and alkenyl diselenocyanates could be efficiently and conveniently obtained in moderate to good yields under mild and metal-free conditions by the simple use of oxone and PhI(OAc)2 as the oxidants.
PSEUDOHALOGEN CHEMISTRY-VII. ADDITION OF THIOCYANOGEN TO ALKYNES

Thiocyanogen does not react with simple alkynes under heterolytic conditions in benzene at 20-25 deg C.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 of thiocyanogen in an initial kinetically-controlled reaction and subsequent thermodynamically-controlled isomerisation of the adducts, is proposed.The influence of substituents on the reaction rates and product ratios is discussed in terms of their steric effects.
