Metal-metal cooperativity is emerging as an important strategy in catalysis. This requires appropriate ligand scaffolds that can support two metals in close proximity. Here we report nickel-promoted formation of a dinucleating planar macrocyclic ligand that can support bimetallic dinickel(II) and dinickel(I) complexes. Reaction outcomes can be tuned by variation of the substituents and reaction conditions to favour dinucleating macrocyclic, mononucleating macrocyclic or conventional pincer architectures.
金属-金属协同作用在催化中正成为一种重要的策略。这需要合适的配体支架，以支持两个金属近距离接近。在这里，我们报告了镍促进的二核平面大环配体的形成，该配体可以支持双金属二镍（II）和二镍（I）配合物。通过改变取代基和反应条件，可以调整反应结果，有利于二核大环、单核大环或传统的夹持型结构。
