摘要

2, 2, 2-Trifluoro-l-(phenylthio) ethyl carbocation (4) has been generated by the reaction of l- chloro-2, 2, 2-trifluoroethyl phenyl sulfide (7b) with ZnC1, in nitromethane or SnCl, in 1, 2- dichloroethane. The carbocation 4 can be trapped with various aromatics bearing electron- donating groups, affording l-aryl-2, 2, 2-trifluoroethyl phenyl sulfide 2 in 37-83% yields. Similarly, allyltrimethylsilane and various nitriles provided the corresponding allylated ...
