A Series of Trigonal Arylimido Iron Complexes and the Influence of Oxidation State and Steric Demand on Reactivity.

ABSTRACT: We describe the reaction between the linear iron(I/II) silylamides [FeL₂]^0,- (L = N{Dipp}SiMe₃) and aryl azides N₃R with different steric demand (R = Ph, 2-Me-C₆H₄ (Tol), 2,4-Me₂-C₆H₃ (Xyl), 2,6-ⁱPr₂-C₆H₃ (Dipp), 2,4,6-ⁱPr₃-C₆H₂ (Tripp)). Obtained trigonal anionic high-spin iron(II) imidyl complexes exhibit long Fe-N bonds of approximately 1.76 Å. In case of the largest substituent (R = Tripp) a slow SiMe₃-shift from the ancillary ligand to the imido nitrogen is observed. In contrast, for the smallest azide (PhN₃) the tetrazenido complex [Fe(η²-κN:¹
