Abstract

ABSTRACT. Heterocyclic pyridazine continues to attract great interest, mainly arising from a large variety of interesting pharmacological activities, herbicides, insecticides, and fungicides. On the other hand, the current interest in selenium-containing heterocycles is a result of their chemical properties and biological activities. In addition to the many recent publications dealing with the pharmacological potential of a selenium compound, new active formulations are an attractive target for chemical research. 2-((3-cyano-4,6-dimethylpyridin-2-yl)selanyl) acetic acid (pyd-Se), 2-((4-cyano-5,6-diphenylpyridazin-3-yl)selanyl)acetic acid (pydz-Se) and 2-((4,6-dimethyl quinolin-2-yl)selanyl)acetic acid (quin-Se) reacts with gold(III) chloride to produce metal ion complexes of specific composition. These synthesized complexes were characterized by elemental analyses, molar conductivity, FTIR, 1H NMR and transmission electron microscopy (TEM) investigations. The complexes were found to have the formulas [Au(pyd-Se)2]Cl, [Au(pydz-Se)2]Cl and Au(quin-Se)2]Cl, respectively. KEY WORDS: Au(III), Organoselenium, Complexation, FTIR, 1H NMR, TEM Bull. Chem. Soc.

金(III)硒有机配合物的合成及光谱研究

摘要杂环吡啶继续引起人们的极大兴趣，主要是由于它具有各种有趣的药理活性，可以作为除草剂、杀虫剂和杀菌剂。另一方面，目前对含硒杂环的兴趣是由于它们的化学性质和生物活性。除了许多最近的出版物处理的药理学潜力硒化合物，新的活性配方是一个有吸引力的目标，化学研究。2-((3-氰-4,6-二甲基吡啶-2-基)selanyl)乙酸(pyd-Se)、2-((4-氰-5,6-二苯吡啶-3-基)selanyl)乙酸(pydz-Se)和2-((4,6-二甲基喹啉-2-基)selanyl)乙酸(quin-Se)与氯化金(III)反应生成特定组成的金属离子配合物。通过元素分析、摩尔电导率、红外光谱(FTIR)、核磁共振氢谱(1H NMR)和透射电镜(TEM)对合成的配合物进行了表征。发现配合物的分子式分别为[Au(pydz-Se)2]Cl、[Au(pydz-Se)2]Cl和Au(quin-Se)2]Cl。& # x0D;关键词:Au(III)，有机硒，络合，FTIR, 1H NMR, TEM 公牛。化学。Soc。中国生物医学工程学报，2016,37(5):1141-1150。& # x0D;DOI: https://dx.doi.org/10.4314/bcse.v37i5.7
