operationally simple synthetic methods for acyl fluorides has always been desirable. We report herein a rapid, simple and efficient acyl fluoride synthesis from carboxylic acids with Cu(O2CCF2SO2F)2 as a deoxofluorination reagent. Notably, Cu(O2CCF2SO2F)2 was readily prepared in large scale from inexpensive starting material, and previously used as a good trifluoromethylating reagent.
