A nucleophilic trifluorovinylation of organothiocyanates catalyzed by tetrabutylammonium fluoride has been developed. In this transformation, a variety of aryl and alkyl thiocyanates reacted with trifluorovinyl trimethylsilane to afford 1,2,2-trifluorovinyl sulphides. This transformation was extended to organic selenocyanates to afford 1,2,2-trifluorovinyl selenides. The presented methodology is simple and mild, and can also be used to prepare 1,2,2-trifluorovinyl sulphoxides from organothiocyanates.

有机硫氰酸酯和硒氰酸酯的三氟乙烯基化合成1,2,2-三氟乙烯基硫化物和硒化物

已经开发了由四丁基氟化铵催化的有机硫氰酸酯的亲核三氟乙烯基化。在该转化中，各种芳基和烷基硫氰酸酯与三氟乙烯基三甲基硅烷反应，得到1,2,2-三氟乙烯基硫化物。该转变扩展为有机硒酸酯，得到1,2,2-三氟乙烯基硒化物。所提出的方法是简单且温和的，并且还可以用于从有机硫氰酸酯制备1,2,2-三氟乙烯基亚砜。
