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.
一种芳基键合的硅亚胺配体 L（L = PhC(tBuN)2SiCH2C(tBu)NAr，Ar = 2,6-iPr2C6H3），允许合成三配位的 Fe(ii)硅酰胺和钢琴凳 Fe(0)二氮杂环戊二烯配合物 LFe[N(SiMe3)2]2（3）和 LFe-N2（4），它们不仅表现出有趣的键合，而且还能在室温下在 1 个大气压的 N2 下催化 N2 的硅烷化，得到高 TON 值的 N(SiMe3)3。
