Epoxidation of Olefins by Molecular Oxygen Over Supported Metal Heterogeneous Catalysts

Autor: Robert J. Angelici, Hanrong Gao

Publikováno v: Synthetic Communications. 30:1239-1247

Molecular oxygen (1 atm) conveniently reacts with olefins in the presence of simple supported metal heterogeneous catalysts and aldehydes (e.g., isobutyraldehyde and benzaldehyde) at room temperature to give epoxides in good yields.
