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.
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.

Gas phase studies of dissociative electron attachment to simple alkyl (CF(3)SO(3)CH(3)) and aryl (C(6)H(5)SO(3)CF(3) and CF(3)SO(3)C(6)H(4)CH(3)) triflates, model molecules of nonionic photoacid generators for modern lithographic applications, were performed. The fragmentation pathways under electron impact below 10 eV were identified

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
