A new method for making acyl fluorides using BrF3

Or Cohen, Revital Sasson, Shlomo Rozen

Research output: Contribution to journalArticlepeer-review


While many carboxylic acids could be converted directly to acyl fluorides by using BrF3, the reaction with acyl chlorides was found to be of a more general nature and yields better results. Surprisingly, reacting t-butyl esters with bromine trifluoride also resulted in acyl fluorides in reasonable yields. The reactions were completed in a few seconds at 0°C.
