Synthesis and Reactivity of Cobalt–Dinitrogen Complexes Bearing Anionic PCP-Type Pincer Ligands toward Catalytic Silylamine Formation from Dinitrogen

A series
of cobalt­(I)–dinitrogen complexes bearing anionic
4-substituted benzene-based PCP-type pincer ligands are synthesized
and characterized. These complexes work as highly efficient catalysts
for the formation of silylamine from dinitrogen under ambient reaction
conditions to produce up to 371 equiv of silylamine based on the cobalt
atom of the catalyst.

本研究合成并表征了一系列带有阴离子型4-取代苯基PCP型钳形配体（PCP-type pincer ligand）的一价钴二氮配合物。该类配合物可作为高效催化剂，在常温常压反应条件下催化以二氮为原料的硅基胺合成反应，以催化剂中的钴原子为基准，硅基胺的最高产量可达371当量。
