摘要

摘要合成了[PdL2Cl2]（I）和[PdL2Вr2]（II）（L 为 5-乙酰基-6-甲基-4-(3-硝基苯基)-1,2,3,4-四氢嘧啶-2-硫酮）的络合物，并通过光谱方法（1Н、13С NMR 和 IR 光谱）对其进行了表征。确定了复合物 I 的晶体结构（CIF 文件 ССDС no. 2233053），其中钯原子与两个配体 L 的两个卤化离子和两个硫原子配位，呈扭曲的方形平面几何结构。通过与相应的卤化钯和含钛沸石 TS-1 的催化活性进行比较，估算了合成的钯（II）配合物在烯丙醇环氧化模型中的催化活性。

Palladium Complexes of Pyrimidine-2-thiones: Synthesis, Structures, and Properties

Complexes [PdL₂Cl₂] (I) and [PdL₂Вr₂] (II) (L is 5-acetyl-6-methyl-4-(3-nitrophenyl)-1,2,3,4-tetrahydropyrimidine-2-thione) are synthesized and characterized by spectral methods (¹Н, ¹³С NMR and IR spectroscopy). The crystal structure of complex I is determined (CIF file ССDС no. 2233053) in which the palladium atom is coordinated by two halide ions and two sulfur atoms of two ligands L in a distorted square planar geometry. The catalytic activity of the synthesized palladium(II) complexes in the model epoxidation of allyl alcohol is estimated in comparison with the catalytic activity of the corresponding palladium halides and titanium-containing zeolite TS-1.

期刊介绍： Russian Journal of Coordination Chemistry is a journal that publishes reviews, original papers, and short communications on all aspects of theoretical and experimental coordination chemistry. Modern coordination chemistry is an interdisciplinary science that makes a bridge between inorganic, organic, physical, analytical, and biological chemistry.
