Oxidative esterification of aldehydes using a recyclable oxoammonium salt



Oxidative esterification of aldehydes using a recyclable oxoammonium salt



Organic Letters 15(9): 2222-2225



A simple, high yielding, rapid route for the oxidative esterification of a wide range aldehydes to hexafluoroisopropyl (HFIP) esters using the oxoammonium salt 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 oxoammonium salt, 1a.
