MONOOXYGENASE-LIKE OXIDATIONS OF OLEFINS AND ALKANES CATALYZED BY MANGANESE PORPHYRINS : COMPARISON OF SYSTEMS INVOLVING EITHER O2 AND ASCORBATE OR IODOSYLBENZENE

A biphasic system using a manganese porphyrin as a catalyst and sodium ascorbate as a reducing agent is able to activate dioxygen and to oxidize olefins selectively into epoxides and alkanes into alcohols and ketones.Its properties and specifities are shown to be different from those of the manganese porphyrin-iodosylbenzene system, suggesting that a manganese -oxo complex is not involved in these O2-dependent oxidations.
