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-甲基锡酯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。

Twenty novel methyldicyclohexyltin carboxylates were prepared and their structurres were characterized with IR, NMR and X-ray diffraction. The results show that the methyldicyclohexyltin fattycarboxylates are five coordinate, carboxylate-bridged polymers, while are aromatic carboxylates are four coordinate. The results of bioassay indicate that these compounds are of high acaricidal, fungicidal and herbicidal activitives.
