Catalytic and asymmetric aziridination of alkenes catalysed by a chiral manganese porphyrin complex

Abstract

A D₄-manganese(III) porphyrin is utilized to catalyze aziridination of styrene-type substrates with enantiomeric excess ranging from 43 to 68%; evidence for a Mn^IV reactive intermediate in the catalysis was obtained from spectroscopic studies and organic product analysis.
