Untangling the catalytic importance of the Se oxidation state in organoselenium-mediated oxygen-transfer reactions: the conversion of aniline to nitrobenzene
Andrea Madabeni, Damiano Tanini, Antonella Capperucci, Laura Orian
Abstract
Se( iv ) seleninic acid is the active catalyst in aniline oxidation by H 2 O 2 due to its favorable peroxide activation kinetics. The slow formation of Se( vi ) selenonic acid and its poorer performance in H 2 O 2 activation hinder its catalytic role.
