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： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
