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