Diiron amido-imido complex [(Cp*Fe)(2)(mu(2)-NHPh)(mu(2)-NPh)]: Synthesis and a net hydrogen atom abstraction reaction to form a bis(imido) complex
A reaction between [Cp*FeCl](x) and LiNHPh (1 equiv to Fe) produces a new paramagnetic Fe(II)-Fe(III) mu 2-amido-mu 2-imido complex [(Cp*Fe)(2)(mu(2)-NHPh)(mu(2)-NPh)] (1), which, upon interaction with 2,2'-azobis(2,4-dimethylvaleronitrile), undergoes a net N-H hydrogen atom abstraction reaction to give a diamagnetic Fe(III) Fe(III) mu(2)-imido dimer [Cp*Fe(mu(2)-NPh)](2) (2). The molecular structures of 1 and 2 have been determined by single-crystal X-ray diffraction.
