  名称：

  邻位钯制的二甲基苄胺配合物，可作为高效的周转催化剂，用于分解P = S杀虫剂。一些含P = S的硫代磷酸酯三酯的甲醇分解的机理研究。

  摘要：

  合成了邻钯配合物Pd（dmba）（py）（OTf）（9）或Pd（N，N-二甲基苄胺）（吡啶）（三氟甲磺酸盐），并研究了其在甲醇中的溶液性质与pH的关系。在中性溶液中，三氟甲磺酸酯从络合物中解离，形成显性形式的Pd（dmba）（py）（HOCH3），在酸性条件下，吡啶解离，形成Pyr-H +和Pd（dmba）（HOCH3）（HOCH3）。在碱性条件下，Pd（dmba）（py）（HOCH3）电离产生Pd（dmba）（py）（-OCH3），吡啶可从中解离，生成双甲氧基桥接的二聚体（Pd（dmba ）（-OCH3））2（15-二聚体），及其单体Pd（dmba）（HOCH3）（-OCH3）。在缓冲条件下的动力学研究表明，9是杀fe硫磷和其他P = S农药甲醇分解的有效催化剂。催化剂的活性形式是碱性的，具有一种缔合的甲醇盐，其表观（s）pK（a）为10.8。对UV / vis光谱随pH的变化进行分析，得出分光光度法（s）pK（a）为10

  Palladacycles 2-4 with C,N-bidentate and N,C,N'-tridentate ligands were prepared and characterized. The X-ray crystal structures of [2,6-bis(N,N-dimethylaminomethyl)phenyl-N,C(1),N'-](aqua)palladium(II) triflate (2), (N,N-dimethylaminobenzyl-C(1),N)(4-trifluoromethylpyridine)(aqua)palladium(II) triflate (3), and (N,N-dimethylaminobenzyl-C(1),N)(4-N,N-dimethylaminopyridine)(aqua)palladium(II) triflate (4), were determined. While 2 is much less active, 3 and 4 effectively catalyze the methanolysis of the P=S pesticides. The catalytic activities were higher with the trifluoromethylpyridine co-ligand as compared to palladacycles containing 4-N, N-dimethylaminopyridine and pyridine co-ligands. (1)H NMR spectra and the catalytic kinetic dependences on concentration and pH revealed that the active species was a pallada-cycle containing one methoxide and one pyridine in the coordination sphere. A plot of the catalytic activity vs. free [pyridine] indicated the participation of a common species. The proposed catalytic mechanism involves a pre-equilibrium binding of the P=S pesticide to palladium(II) center followed by dissociation of the pyridine and subsequent cleavage of the PeOAr unit through the intramolecular displacement on phosphorus by the adjacent Pd-coordinated methoxide.
