Abstract

An advanced intermediate: A nonheme iron(IV) oxo complex [Fe IV(O)(bqen)(L)]n+ (bqen=N,Nr-dimethyl-N,N r -bis(8-quinolyl)ethane-1,2-diamine, L=CH3CN or CF 3SO3-) 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).
