摘要：

Silver(I) trifluoromethanethiolate reacts with halotrimethylsilanes to produce silver halide, fluorotrimethylsilane and an oligomeric species of formula (CS)(3)(SCF3)(2).Variable temperature F-19 NMR spectroscopy reveals that the reaction proceeds via trimethylsilyl trifluoromethyl sulfide (Me3SiSCF3), which rapidly decomposes on warming. This acts as a source of nucleophilic trifluoromethanethiolate, reacting with highly activated haloaromatics to produce trifluoromethyl aryl sulfides. (C) 1998 Elsevier Science S.A.
