Abstract

Abstract : An operationally simple and highly selective method for the Ni-catalyzed decarboxylation of redox active esters (RAEs) derived from fatty acids under remarkably mild conditions is described herein. Abstract : An operationally simple and highly selective method for the decarboxylation of fatty acids under remarkably mild conditions is described herein. The activation of the aliphatic carboxylic acids by esterification with N -hydroxyphthalimide (NHPI) enabled efficient deoxygenation to synthesize n -alkanes in up to 67% yield, employing inexpensive PMHS as a hydrogen source, NiCl2 ·6H2 O, bipyridine, and zinc in THF. In contrast to the conventional thermo-catalytic approaches, this protocol does not require high temperature and high pressure of hydrogen gas to deoxygenate biomass-derived carboxylic acids, thus representing an attractive alternative for producing drop-in biofuels.
