The synthesis of a tridentate NNN ligand incorporating an amidoquinoline and an iminophosphorane (LRH; R = Ph, Cy) was carried out. Coordination to PdII and NiII precursors gave, as expected, square-planar complexes of the general formula [LRMCl]. The most surprising result came from the reaction of LPhH with [Ni(COD)2], which gave a NiII phenyl complex bearing a tridentate amidoquinoline-aminophosphine ligand. This rearrangement would result from a proton transfer assisted by the Ni0 on stabilization by a phenyl substituent at the phosphorus, as suggested by DFT calculations and complementary experiments. This nickel phenyl complex formed the corresponding benzoyl complex under a CO atmosphere.

三齿NNN配体与氨基喹啉和亚氨基磷烷：合成和配位钯和镍中心。
进行了三齿NNN配体的合成，该配体包含有酰胺基喹啉和亚氨基磷烷（L R H； R = Ph，Cy）。如所预期的，与Pd II和Ni II前体的配位给出了通式[ L R MCl]的方平面络合物。最令人惊讶的结果来自L Ph H与[Ni（COD）2 ]的反应，生成带有三齿酰胺基喹啉-氨基膦配体的Ni II苯基配合物。这种重排将由Ni 0辅助的质子转移引起如DFT计算和补充实验所建议的那样，通过磷上的苯基取代基来稳定化。该镍苯基络合物在CO气氛下形成相应的苯甲酰基络合物。
