complexes revealed that the palladium in [LnPdCl]ClO4 (Ln = L1, L2, L3) and [LnPdCl2] (Ln = L4, L5) formed a slightly distorted square planar geometry involving two nitrogens of iminomethylpyridine ligand, one X, and one or two chlorides. The N,N′,X-tridentate complex [L2PdCl]ClO4 and the N,N′,X-bidentate complex [L5PdCl2] showed high catalytic activity for polymerization of methyl methacrylate in the
[Pd(CH3CN)2Cl2]与N-官能团取代的2-亚氨基甲基吡啶和2-亚氨基甲基喹啉反应生成N,N',X-二齿Pd(II)配合物和N,N',X-三齿Pd( II) 复合物取决于亚胺部分氮上的官能团取代。例如,N,N-二甲基-3-((吡啶-2-基亚甲基)氨基)丙-1-胺(L1)、N,N-二甲基-3-((喹啉-2-基亚甲基)氨基)丙- 1-胺(L2)和N-(3-(甲硫基)丙基)-1-(吡啶-2-基)甲胺(L3)在存在下以N,N',X-三齿模式与钯配位NaClO4 分别以高产率生成两个稠环金属环 [(NN'X)PdCl]ClO4 配合物,即 [LnPdCl]ClO4 (Ln = L1, L2, L3)。然而,N-甲基-N-(3-((吡啶-2-基亚甲基)氨基)丙基)苯胺(L4)和N-(3-甲氧基丙基)-1-(吡啶-2-基)甲胺(L5)产率(以不存在 NaClO4) N,N',X-双齿金属环 [(NN')PdCl2]
