aldehydes to hexafluoroisopropyl (HFIP) esters using the oxoammoniumsalt 4-acetylamino-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate (1a) is reported. These esters can be readily transformed into a variety of other functional groups. The spent oxidant (1b) can be recovered and conveniently reoxidized to regenerate the oxoammoniumsalt, 1a.
