Abstract

A practical synthesis of trifluoromethanesulfonate esters by reaction of orthoformate esters with triflic anhydride is described. The solvent-free method featured mild condition, short time, high yield, simple operation and broad substrate scope. The in situ generated trifluoromethanesulfonate ester is highly reactive alkylating agent, providing triflate ionic liquid in excellent yield via a one-pot procedure.

Key words： trifluoromethanesulfonate ester; orthoester; triflic anhydride; one-pot alkylation
