Nitrous Oxide Oxidation of Olefins Catalyzed by Ruthenium Porphyrin Complexes.

In the presence of a catalytic amount of dioxo(tetramesitylporphyrinato)ruthenium(VI) complex, nitrous oxide (N2O) oxidized trisubstituted olefins into the corresponding epoxides in good-to-high yields with high selectivities.
