本文合成了15个含锡锗杂恶唑烷化合物,N(CH~2CH~2O)~3GeCHR^1CH~2CO~2SnR(R=Cy~3, Bu~3^n, Ph~3, Cy~2Bu^n,CyBu~2^n; R^1=H, C~6H~5, p-CH~3C~6H~4, p-ClC~6H~4)。通过对产物的IR、1^HNMR、MS和元素的分析测定, 确定了它们的组成和结构。三丁基锡羧酸酯具有五配位的结构。生物活性测定结果表明, 这些化合物具有较好的杀螨和除草活性, 同时对植物病原菌也有一定的防治效果。

Fifteen new title compounds N(CH2CH2O)3GeCHR1CH2CO2SnR3 (R = Cy, Bu, Ph, R3 = Cy2Bu, CyBu2, R1 = H, Ph, p-CH3C6H4, p-ClC6H4) were synthesized and their structures identified by IR, 1H NMR, MS and elemental anal. The compounds may be five-coordinate when R = Bu, whereas the others are four-coordinate. From preliminary biol. tests these compounds have good acaricidal and herbicidal activities and display some fungicidal activity for plant diseases.
