Perfluorohydrocarbon sulfenyl silver reagent and preparation and application methods thereof

The invention discloses a perfluorohydrocarbon sulfenyl silver reagent and a preparation and application method thereof, and belongs to the field of organic chemistry. According to the method, an intermediate substance thio perfluoroacetate is prepared through the reaction of (trifluoromethyl) trimethylsilane, cesium fluoride and carbon disulfide, and then the thio perfluoroacetate and silver fluoride are subjected to a desulfurization and fluorination reaction, so that the perfluoroethylthio silver reagent is successfully obtained. The perfluoroethylthio silver reagent obtained in the invention is taken as a reactant and acts with an N-halogenated o-dicarboximide compound to obtain an electrophilic N-perfluoroethylthio-o-dicarboximide reagent, so that the types of pentafluoroethylthio reagents are enriched; meanwhile, the perfluoroethylsulfenyl silver reagent has potential application value in the fields of drug research and development, organic synthesis, antibacterial coatings and the like. 本发明公开了一种全氟烃硫基银试
