Abstract
- A novel magnetically recoverable catalyst in which protonated peroxotungstate was immobilized into a network of cross-linked chitosan with a superparamagnetic Fe3O4 core (Fe3O4–CS/HWO) was prepared, characterized and used in oxidation reactions. With H2O2 as oxidant, a wide range of substrates including olefins, sulfides, amines and allylic alcohols could be oxidized selectively, exhibiting a relatively high utilization percentage of H2O2. Due to the existence of peroxotungstate as well as the magnetic core, both improved catalytic performance and facilitated separation were achieved for the reaction process. [ABSTRACT FROM AUTHOR]
