  Design and Synthesis of a New Binucleating Ligand via Cobalt-Promoted C−N Bond Fusion Reaction. Ligand Isolation and Its Coordination to Nickel, Palladium, and Platinum

  摘要：

  A new polydentate bridging ligand, NH4C5N=NC6H4N(H)C5H4N (HL2), is synthesized by the cobalt-mediated phenyl ring amination of coordinated NH4C5N=NC6H5. The green cobalt complex intermediate [Co(L-2)(2)](ClO4), [1](ClO4), and the free ligand HL2 were isolated and characterized. The X-ray structure of [H2L2] (ClO4) is reported. The ligand, upon deprotonation, behaves as a bridging ligand. It reacts with NiCl2-6H(2)O and Na-2[PdCl4] to produce dimetallic complexes, [Ni2Cl2(L-2)(2)], 2, and [Pd-2(L-2)(2)](ClO4)(2), [3](ClO4)(2), respectively. X-ray structures of these two dimetallic complexes are reported. The structure of the dinickel complex, in particular, is unique. In this complex, the two deprotonated secondary amine nitrogens of the two [L2](-) igands bind to two nickel centers simultaneously forming a planar Ni2N2 arrangement. The complex [3](ClO4)(2) is diamagnetic while the complex 2 is paramagnetic. The results of magnetic measurements on the dinickel complex in the temperature range 1.8-300 K are reported. The system can be described as a single spin S = 2 in the low-temperature range T much less than J/k whereas at high temperatures, T much greater than J/k, it behaves as two independent spins S = 1.The reaction of [L-2](-) with K-2[PtCl4], however, yielded a monometailic platinum complex, [PtCl3(L-2)], 5, where the pyridyl nitrogen of the aminopyridyl function remained unused. The X-ray structure of the complex 4a is reported. The bond lengths along the ligand backbones in all the complexes indicate extensive pi-delocalization. Spectral data of the complexes are reported and compared.

  In an unusual reaction of [Pd(L1)Cl2] (L1 = 2-(arylazo)pyridine) with amines, a new series of palladium complexes [Pd(L2•–)Cl] (L2 = 2-((2-amino)arylazo)pyridine) (1a–1h) were isolated. The complexes were formed via N–H and N–C bond cleavage reactions of 1°/2° and 3° amines, respectively, followed by regioselective aromatic ortho-C–N bond formation reaction and are associated with ortho-C–H/ortho-C–Cl

  在[Pd（L 1）Cl 2 ]（L 1 = 2-（芳基偶氮）吡啶）与胺的不寻常反应中，一系列新的钯配合物[Pd（L 2•–）Cl]（L 2 = 2- （（2-氨基）芳基偶氮）吡啶）（1a – 1h）被分离出来。将复合物通过1°/ 2°和3°胺，分别，随后区域选择性芳香N-H和N-C键的断裂反应形成的邻-C-N键形成反应，并且与相关联的邻- C-H /邻位C–Cl键激活。发现包括芳族和脂族在内的多种胺可有效地生产空气稳定的络合物。通过它们的X射线结构确定来证实所得复合物的身份。还努力了解该反应的机理。进行了一系列实验，这些实验指向初始配体还原，然后是配体内电子转移。检查这些配合物的结构参数（1）表明原位生成的配体与Pd II配位中心是这些空气稳定的单自由基配合物的骨干。通过各种光谱技术，包括循环伏安法，可变温度磁化率测量，电子顺磁共振和紫外可见光谱，进一步研究了分离出的复合物的分子和电子结构
