Abstract

Reaction of 2 equiv of 1,2-bis(dimethylsilyl)benzene with [Fe(mesityl) ₂]₂ in aromatic solvent under a nitrogen atmosphere afforded the dinuclear bis(silyl)iron complexes [(η⁶-arene) Fe(Me₂SiC₆H₄SiMe₂)] ₂(μ-η¹:η¹-N₂) (1), which have an end-on-bound bridging dinitrogen ligand. The dinitrogen unit easily dissociated from the Fe center to generate the mononuclear (η⁶- arene)Fe^II(Si)₂L or (η⁶-arene)Fe ^IV(Si)₂H₂ complexes by the reactions with CO, PPh₃, and H₂.
