C–N bond hydrogenolysis of aniline and cyclohexylamine over TaOx–Al2O3†
Abstract
TaOx grafted onto Al2O3 is investigated for C–N bond cleavage of amines under H2 pressure. Heteroaromatics such as aniline are stoichiometrically denitrogenated at high temperature, while cyclohexylamine is catalytically denitrogenated. UV-visible and X-ray photoelectron spectroscopy indicate the formation of a stable Ta–N species in the former case.
