NEW INSIGHT INTO REACTION OF IRON(III)-PEROXIDE ADDUCT WITH ALKANES -AN ALTERNATIVE MODEL FOR CYTOCHROME-P-450 AND METHANE MONOOXYGENASE

A new mechanism for alkane functionalization by iron(III)-peroxide add ucts was proposed, and the importance of electrophilic nature of the m etal-peroxide adduct with eta(1)-coordination mode was emphasized. Thi s idea suggests that formation of high-valent iron-oxo species occurs most likely when the metal-peroxide intermediate is activated through electronic interaction with both the peripheral organic group and subs trate; the latter two act as an electron donor to the peroxide adduct.
