It was also used in Takahashi Taxol total synthesis and in chemical glycosylation reactions. [5]Trimethylsilyl trifluoromethanesulfonate has a variety of other specialized uses.
Trifluoromethanesulfonic anhydride, also known as triflic anhydride, is the chemical compound with the formula (CF 3 SO 2) 2 O. It is the acid anhydride derived from triflic acid.
Sodium trifluoromethanesulfinate (CF 3 SO 2 Na) is the sodium salt of trifluoromethanesulfinic acid. Together with t-butyl hydroperoxide, an oxidant, this compound was found to be a suitable reagent for introducing trifluoromethyl groups onto electron-rich aromatic compounds by Langlois; this reagent is also known as the Langlois reagent.
