Selective epoxidation of olefinsby hydrogen peroxide in water using a polyoxometalate catalyst supported on chemically modified hydrophobic mesoporous silica gel

摘要

A new heterogeneous catalyst prepared by immobilisation of polyoxometalates onchemically modified hydrophobic mesporous silica gel has been successfully applied to the selective epoxidation of olefins with 15% aqueous H_2O_2 without the use of organic solvent.
