Enantiomeric epoxidation of 4-chlorostyrene with H2O2 catalysed by robust chloro manganese(III)meso-5,10,15,20-tetrakis [2-chloro-6-(2,3,4,6-tetraacetyl-O-β-glucosyl)phenyl] porphyrins
Abstract
Three new chiral porphyrins bearing chloro and glucosyl groups are obtained by Lindsey's method; their chloro manganese(III) complexes are robust catalysts for the asymmetric epoxidation of 4-chlorostyrene with diluted hydrogen peroxide.
