Epoxides are an important class of industrial chemicals that have been used as chemical intermediates. Catalytic epoxidation of olefins affords an interesting technology for their production. This review summarizes recent developments for the epoxidation of olefins with hydrogen peroxide catalyzed b

The highest turnovers reported so far in the epoxidation of olefins with hvdroaen peroxide are obtained under homoaeneous conditions with trioctyimethyla&nonium tungstate complexed by lipophilic neutral or anionic phosphorus ligands containing the P=O subunit.
Peroxotungstic acid and quaternary ammonium peroxotungstic salts when complexed to organophosphorus(V) ligands exhibit enhanced reactivity and selectivity in the epoxidation of unsaturated alcohols with hydrogen peroxide. The organophosphorus ligands contain the phosphoryl O=P= subunit as complexing
