Abstract

Regenerable and reusable dendritic catalysts have been synthesized by the ionic assembly of polyammonium dendrimers and polyoxometalate (POM) trianionic units. These dendrimers (see example depicted, in which the POM is [PO 4{WO(O2)2}4]3-) are found to catalyze, at ambient temperature, the quantitative epoxidation of olefins by H2O2 in water/ CDCl3 and the selective and quantitative oxidation of thioanisole to its sulfone.
