摘要：

Iron porphyrins with halogen substituents at the beta-pyrrole positions are found to be poorer catalysts for hydroxylation of ethylbenzene by ozone than the corresponding unsubstituted complexes. For the best catalyst, the chloroiron(III) complex of tetra-(2,6-dichlorophenyl)porphyrin, the initial process proceeds in quantitative yields relative to ozone. Inactivation of the catalytic process after formation of about 100-140 mol alcohol/mol catalyst is attributed to product inhibition.
