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