Reactive Intermediates in Oxygenation Reactions with Mononuclear Nonheme Iron Catalysts


  • The research at EWU was supported by KOSEF/MOST through the CRI Program and the WCU project, Korea, and that at Stanford University by NIH grants RR-01209 (K.O.H.) and GM 40392 (E.I.S.). SSRL operations is funded by the US DOE BES, and the SSRL SMB program by NIH NCRR BTP and DOE BER. The project described was supported by grant no. 5 P41 RR001209 from the National Center for Research Resources (NCRR), a component of the National Institutes of Health (NIH), and its contents are solely the responsibility of the authors and do not necessarily represent the official view of the NCRR or the NIH.


An advanced intermediate: A nonheme iron(IV) oxo complex [FeIV(O)(bqen)(L)]n+ (bqen=N,N′-dimethyl-N,N′-bis(8-quinolyl)ethane-1,2-diamine, L=CH3CN or CF3SO3) activates the C[BOND]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).
