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.
已经开发了烯烃的简单且有效的硫氰基或异硫氰基-苯基硒烯基化。当用[双(乙酰氧基)碘]苯,三甲基甲硅烷基异硫氰酸酯或硫氰酸钾和二苯基二硒化物处理烯烃时,会发生反应。单取代和二取代的烯烃导致形成1,2-苯基硒代硫氰酸酯,而更多取代的烯烃和苯乙烯则仅生成1,2-苯基硒代异硫氰酸酯。总体转化表示将PhSeSCN加到由上述试剂组合原位产生的烯烃双键上。
