Abstract The synthesis of diethyl (pyridin-2-, -3-, -4-ylmethyl)phosphate (2-pmOpe, 3-pmOpe, 4-pmOpe) ligands and their palladium (II) complexes of general formula trans-[PdCl2L2] (L = 2-pmOpe, 3-pmOpe,4-pmOpe) has been described. Pyridine phosphate derivatives were synthesized via the condensation of phosphorochloridic acid diethyl ester with an appropriate pyridinylmethanol in the presence of triethylamine
摘要合成了磷酸二乙酯(吡啶-2-,-3-,-4-基甲基)(2-pmOpe,3-pmOpe,4-pmOpe)配体及其通式为-[PdCl2L2]的钯(II)配合物已经描述了(L = 2-pmOpe,3-pmOpe,4-pmOpe)。在三乙胺的存在下,通过使磷酸氯二乙酯与适当的吡啶二甲基甲醇缩合,合成吡啶磷酸酯衍生物。该化合物已通过IR,远红外,1H NMR,31P NMR,31P CP-MAS NMR和元素分析进行了鉴定和表征。介绍了通过X射线衍射法测定的钯(II)配合物的晶体和分子结构,即[PdCl2(2-pmOpe)2]和[PdCl2(4-pmOpe)2]。在两种结构中,Pd(II)离子均由两个氯原子和两个吡啶氮原子四配位。
