Abstract

An arene-tethered silylene ligand, L (L = PhC(^tBuN)₂SiCH₂C(^tBu)NAr, Ar = 2,6-ⁱPr₂C₆H₃), allowed the synthesis of three-coordinate Fe(II) silylamido and piano-stool Fe(0) dinitrogen complexes LFe[N(SiMe₃)₂]₂ (3) and LFe-N₂ (4), which not only exhibit interesting bonding but also enabled the catalytic silylation of N₂ to yield N(SiMe₃)₃ under 1 atm of N₂ at room temperature with high TONs.
