Reactive intermediates in oxygenation reactions with mononuclear nonheme iron catalysts

Abstract

An advanced intermediate: A nonheme iron(IV) oxo complex [Fe IV(O)(bqen)(L)] n+ (bqen=N,N r-dimethyl-N,N r -bis(8-quinolyl)ethane-1,2-diamine, L=CH 3CN or CF 3SO 3-) activates the C - H bonds of alkanes and alcohols by a hydrogen-atom abstraction mechanism. The catalytic oxidation of these species is proposed to occur through a nonheme iron(V) oxo species, with a high reactivity in oxidation reactions (see picture). © 2009 Wiley-VCH Verlag GmbH & Co.
