synthesized four nickel complexes of naphthalimide based organic ligands. These complexes catalyze the hydrolysis of phosphorothioate bonds of organophosphates in an aqueous medium. The metal complexes [Ni(L1)2]–[Ni(L4)2]} were synthesized by the electrochemical method and characterized using single‐crystal X‐ray crystallography and mass spectrometry. Analytical techniques revealed that complexes are mononuclear
为了将剧毒农药降解为危害较小的组分,我们合成了四种萘二甲酰亚胺基有机配体的镍配合物。这些络合物在水性介质中催化有机磷酸酯的硫代磷酸酯键的水解。金属配合物[Ni(L 1)2 ]-[Ni(L 4)2 ]}是通过电化学方法合成的,并利用单晶X射线晶体学和质谱法进行了表征。分析技术表明,复合物是单核的并且具有八面体的几何形状。使用31评估了毒死pho和甲基对硫磷的降解率P NMR和LC-MS色谱图。质谱证实了毒死pho在配合物催化降解后的副产物。发现在与催化剂孵育50分钟后,毒死py降解为3,5,6-三氯吡啶-2--2-醇。但是,甲基对硫磷仅需20分钟即可水解成副产物。此外,在金属络合物存在下对农药进行了乙酰胆碱酯酶的抑制试验,并记录了令人感兴趣的结果。
