摘要：

pi-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. In the complex system, transition metals are considered to electronically interact through a pi-conjugate polymer chain. Protonic acid doping and transition metal doping play an important role in reversible redox processes of polyanilines.
