摘要

用大体积二胺配体还原MnII前体，可以获得已知最长的Mn-Mn键配合物，并在高自旋MnI中心获得罕见的N2活化。虽然对Mg类似物的观察可以得出一些有指导意义的相似之处，但在各自的MnI中间体中填充d轨道的可及性导致对苯进行氧化加成的独特行为。

Steric Control in Low-Valent Mn Diamide Complexes: Contrasting Magnesium and Manganese in N₂ and Benzene Activation.

Reduction of Mn^II precursors with bulky diamide ligands provided access to a complex with the longest known Mn-Mn bond and to a rare example of N₂ activation at high-spin Mn^I centers. While some instructive parallels can thus be drawn to observations made for Mg analogues, the accessibility of filled d orbitals in the respective Mn^I intermediates leads to a distinct behavior toward benzene that undergoes an oxidative addition.
