An easy access to polyhalogenated metalloporphyrins covalently bound to polymeric supports as efficient catalysts for hydrocarbon oxidation

Abstract

Reaction of silica, montmorillonite and polystyrene bearing amino functions with several polyhalogenated metalloporphyrins gave an easy one-step access to new supported catalysts, owing to a selective nucleophilic substitution of the para-halogen atoms of the porphyrin meso-aryl groups by the polymer amine function; these catalysts were very active for cyclooctene epoxidation and alkane hydroxylation by PhlO.
