Trimethylsilyl tnflate

Another useful reagent for the preparation of alkynyl lodonium Inflates is [cyano(trifluoromethylsulfonyloxy)(phenyl)]iodine [/i7, 138, 139, 140] prepared from iodosobenzene, trimethylsilyl tnflate, and trimethylsilyl cyanide (equation 71). This reagent reacts with various stannylacetylenes under very mild conditions to form the corresponding alkynyl iodonium salts in high yields [139] (equation 72)... 

Recently, several more effective activators have been introduced, including NBS [35], methyl tnflate [38], dimethyl(methy]thio)sulfonium triflate (DMTST) [39], A-iodo-succinimide-triflic acid (NIS-TfOH) [40], and trimethylsilyl triflate (TMSOTf) [41], The...
