摘要

我们报告了由双膦配体（depe）和双 NHC 配体支持的杂环铁配合物的合成。与同色（即 Fe(depe)2L）变体相比，混合配体组可以获得高度活化的 N2 和 CO 的铁（0）加合物。计算和实验研究表明，混合配体组扭曲了几何和电子结构，产生了一种异常碱性的铁。虽然质子化作用发生在铁上，但 Fe(0)N2 复合物的硅烷化作用产生了高度活化的硅烷二氮[FeNNSiMe3]+ 复合物。

Synthesis of heteroleptic bis-phosphine bis-NHC iron (0) complexes: a strategy to enhance small molecule activation

We report the synthesis of heteroleptic iron complexes supported by both a bis-phosphine ligand (depe) and a bis-NHC ligand. The mixed ligand sets provide access to iron (0) adducts of N₂ and CO that are highly activated, in comparison to homoleptic (i.e. Fe(depe)₂L) variants. Computational and experimental studies revealed the mixed ligand set distorts the geometric and electronic structure to yield an unusually basic iron. Although protonation occurred at Fe, silylation of the Fe(0)N₂ complex afforded a highly activated silyldiazenido [FeNNSiMe₃]⁺ complex.
