Highly Efficient Method for Epoxidation of Olefins with Molecular Oxygen and Aldehydes Catalyzed by Nickel(II) Complexes

Article abstract of DOI:10.1246/cl.1991.1

In the presence of a catalytic amount of a bis(1,3-diketonato)nickel(II) complex, trisubstituted and exo-terminal olefins or norbornene analogues are smoothly monooxygenated into the corresponding epoxides in high to quantitative yields on treatment with aldehyde under an atmospheric pressure of oxygen at room temperature.
