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.

A simple, metal-free route for the oxidative esterification of aldehydes to yield hexafluoroisopropyl esters is reported. The methodology employs sodium persulfate and a catalytic quantity of a nitroxide and is applicable to aromatic, heteroaromatic, and aliphatic aldehydes.
