PMID: 25495541
Org Lett. 2014 Dec 19;16(24):6484-7. doi: 10.1021/ol503345h. Epub 2014 Dec 11.

The oxidation of primary amines using a stoichiometric quantity of 4-acetamido-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate (1) in CH2Cl2-pyridine solvent at room temperature or at gentle reflux affords nitriles in good yield under mild conditions. The mechanism of the oxidation, which has been...

J Org Chem. 2004 Jul 23;69(15):5116-9. doi: 10.1021/jo049461j.

The use of the oxidant 4-acetylamino-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate in combination with pyridine for the oxidative, dimeric esterification of primary alcohols is described. The ester is the predominant product of the reaction with alcohols containing a beta oxygen. In the absence...
