Cobalt-Tetraamide-Phthalocyanine (CoTaPc) immobilized onto magnetic Fe 3 O 4 chitosan microspheres (Fe 3 O 4 /CTO) was synthesized via a simple immersion method, which is an efficient catalyst for the oxidation of cyclic ketones to lactones with O 2 /benzaldehyde as the oxidant. The CoTaPc-Fe 3 O 4 /CTO catalyst was applied for the first time in the Baeyer-Villiger (B-V) oxidation reaction. Characterization results obtained from X-ray diffraction, UV-vis, Fourier transform infrared, and scanning electron microscopy showed that the combination of CoTaPc and magnetic Fe 3 O 4 /CTO microspheres was achieved. The catalyst could be easily separated from the reaction system with an external magnet and reused several times without the remarkable loss of activity. In addition, a possible radical mechanism for the B-V oxidation in this catalytic system is proposed and verified by controlled experiments.
