Sodium Periodate Epoxidation of Alkenes Catalysed by Manganese Porphyrins
Abstract
Epoxidation of alkenes with different electronic and steric properties has been performed with high selectivity by sodium periodate in the presence of acetatotetraarylporphinatomanganese(III) complexes containing electron releasing or withdrawing groups at the ortho positions of the aryl rings, in a two-phase (CH2Cl2–H2O) medium at 24±2°C.
