Torque是一个已经商品化的农用高效杀螨剂.Tacke等首次合成了含硅的类似物Sila Torque(分子式为[(PhMe_2SiCH_2)_3Sn]_2O),同样具有高效杀螨活性.我们曾经报道过三[(苯基二甲硅基)亚甲基]锡羧酸盐的合成和结构的研究,发现这类化合物具有与Torque相类似的生物活性,且药效延长.本文试图通过一个苯基代替与硅相连的一个甲基.改变硅烷基组成,观察其对中心锡原子的配位及生物活性的影响,首次报道了双[三(甲基二苯硅基)亚甲基] Torque is a commercially available agricultural acaricides and Tacke et al first synthesized the analogue Sila Torque (molecular formula [(PhMe_2SiCH_2) _3Sn] _2O), which is also highly effective against acaricide.We have reported three [ (Phenyldimethylsilyl) methylene] tin carboxylate and found that these compounds have biological activity similar to that of Torque, and the drug efficacy is prolonged.This paper attempts to use a phenyl instead of silicon Linked to a methyl group to change the composition of the silane group to observe its central tin atom coordination and biological activity, the first report of bis [tris (methyldiphenylsilyl) methylene]
