THE SELECTIVITIES AND THE MECHANISM ON HIGHLY EFFICIENT EPOXIDATION OF OLEFINS WITH 2,6-DISUBSTITUTED PYRIDINE N-OXIDES CATALYZED BY RUTHENIUM PORPHYRIN
Several remarkable selectivities in competitive epoxidations using a ruthenium porphyrin /2,6-disubstituted pyridine N-oxide system were observed. The proposal that the active intermediate of this system differed from the trans-dioxo complex of ruthenium porphyrin was indicated.
