A novel synthetic metal catalytic system

摘要

π-Conjugate polymers, polyanilines and polypyrroles, served as catalysts in dehydrogenative oxidation reactions of benzylamines, 2-phenylglycine, and 2,6-di-tert-butylphenol under oxygen. The catalytic activity was controlled by protonic acid doping. The reversible redox of the polyaniline Catalyst under oxygen was supported by UV-visible spectroscopy. Polyaniline and transition metal Such as copper(II) chloride or iron(III) chloride formed a complex, which was effective in the Dehydrogenative oxidation of cinnamyl alcohol or mandelic acid.
