Ring-opening of 1-CF 3 -substituted epoxy ethers with carboxylic acids was achieved in Et 3 N as solvent, and α-CF 3 -substituted acyloins and corresponding esters were obtained in good yields. In hexafluoro-2-propanol (HFIP) as solvent, the carboxylic acids acted as nucleophiles, and α-carbonyloxy
