在温和的条件下，P2 N2配体的P-C和C-H键发生不寻常的断裂，形成了一种以C，P，P-三齿配位模式为特征的亚胺甲酰镍酸盐.通过NMR和单晶X-射线衍射分析表征了[Ni（P2 N2）（diphosphine）]（2+）配合物和甲酰基镍酸亚胺盐的结构。采用密度泛函理论（DFT）研究了P-C/C-H键断裂的机理，包括C-H键断裂、氢化物旋转、Ni-C/P-H键形成和P-C键断裂.
Unusual cleavage of P-C and C-H bonds of the P2 N2 ligand, in heteroleptic [Ni(P2 N2 )(diphosphine)](2+) complexes under mild conditions, results in the formation of an iminium formyl nickelate featuring a C,P,P-tridentate coordination mode. The structures of both the heteroleptic [Ni(P2 N2 )(diphosphine)](2+) complexes and the resulting iminium formyl nickelate have been characterized by NMR spectroscopy and single-crystal X-ray diffraction analysis. Density functional theory (DFT) calculations were employed to investigate the mechanism of the P-C/C-H bond cleavage, which involves C-H bond cleavage, hydride rotation, Ni-C/P-H bond formation, and P-C bond cleavage.
