ABSTRACT:
A process for preparing fluorocarbon fluoroalkanesulfonates comprises (a) forming a mixture comprising at least one fluoroalkanesulfonyl halide, e.g., perfluoromethanesulfonyl fluoride, at least one fluorocarbon-substituted carbinol, e.g., 1,1-dihydroperfluorobutoxyethoxyethanol, and at least one base, e.g., triethyl amine; and (b) allowing the mixture to react in the absence of solvent at a temperature below ambient. The process is volume-efficient and provides high yields of fluorocarbon fluoroalkanesulfonates useful as intermediates in, e.g., drug synthesis.
