Notes:
---A simple and efficient thiocyano- or isothiocyano-phenylselenenylation of alkenes has been developed. The reactions occur when alkenes are treated with [bis(acetoxy)iodo]benzene, trimethylsilyl isothiocyanate or potassium thiocyanate and diphenyl diselenide. Mono- and disubstituted alkenes led to the formation of 1,2-phenylseleno-thiocyanates, whereas both more-substituted alkenes and styrenes gave exclusively 1,2-phenylseleno-isothiocyanates. The overall transformation represents the addition of PhSeSCN to the olefinic double bonds, in situ generated by the above reagents combination.
