本文合成了未见文献报道的二环己基-甲基锡氧化物及其二十个羧酸酯衍生物,经红外、核磁及X射线衍射分析确定了化合物的结构.结果表明,所合成的二环己基-甲基锡脂肪酸酯为分子间氧桥相连的五配位聚合结构,而取代苯甲酸酯则为单分子变形四面体结构.化合物的生物活性测定结果表明,这是一类具有高效杀螨、杀菌及除草活性的有机锡化合物. In this paper, dicyclohexyl-methyltin oxide and its twenty carboxylic acid ester derivatives have been synthesized, and their structures have been confirmed by IR, NMR and X-ray diffraction. The results show that the synthesized bis Cyclohexyl-methyl tin fatty acid ester is a five-coordinate polymeric structure linked by intermolecular oxygen bridges, while the substituted benzoate is a single-molecule deformed tetrahedron. The bioassay results of the compounds show that this is a class of Efficient killing acaricidal, bactericidal and herbicidal activity of organic tin compounds.
