一般描述

Methyl trifluoromethanesulfonate (Methyl triflate) is a strong methylating agent. It is also a powerful alkylating agent and a strong irritant.
Shown to be the most effective monomethylating agent in reactions with potassium enolates.
Useful methylation reagent for the conversion of amines to methyl ammonium triflates.

应用

Methyl trifluoromethanesulfonate was used in the synthesis of 2-Benzyloxy-1-methylpyridinium trifluoromethanesulfonate.

Glycosylation of a disaccharide containing N-acetylglucosamine with rhamnosyl and mannosyl trichloracetimidates under triethysilyl triflate catalysis led to the competitive formation of glycosyl imidates. While the rhamnosyl imidate could be rearranged to the thermodynamically favored trisaccharide, the mannosyl analogue was resistant

Aryltrimethylammonium triflates and tetrafluoroborates were found to be highly reactive electrophiles in the Pd-catalyzed cross coupling with aryl Grignard reagents. The coupling reactions proceed at ambient temperature with a nearly stoichiometric quantity of Grignard reagent, and diverse functionality is tolerated.
