A novel synthetic metal catalytic system for dehydrogenative oxidation based on redox of polyaniline

Abstract

Polyaniline serves as a synthetic metal catalyst with reversible redox under oxygen to induce dehydrogenative and/or decarboxylative oxidation of benzylamines and 2-phenylglycine into the corresponding imines and, in combination with copper(II) chloride or iron(III) chloride, dehydrogenation of cinnamyl alcohol into cinnamaldehyde possibly due to complexation.
