Baeyer-Villiger Oxidation of Ketones with Hydrogen Peroxide Catalyzed by Chitosan-Supported Dendritic Sn Complexes

Dendritic Sn complexes were successfully incorporated to chitosan by solid phase synthesis methodology. The polymer-supported catalysts exhibited promising catalytic performance for the Baeyer-Villiger oxidation of ketones in the presence of hydrogen peroxide. The influence of reaction temperature, reaction time, the amount of catalyst used, and solvents on the catalytic activity was investigated systematically. Notably, the catalysts can be prepared in large scale in a simple manner with low-cost materials and also can be recycled for times.
