本文合成了二十个混合甲基二环己基锡取代苯氧乙酸酯。研究了这些化合物的IR, NMR (^1H, ^1^3C, ^1^1^9Sn), 结果表明, 除邻甲氧基苯氧乙酸酯外, 这些化合物都可能是以羰基氧为桥连的五配位聚合有机锡化合物。^1^1^9Sn NMR的研究结果表明, ^1^1^9Sn化学位移与苯环上取代基有一线性关系: δ^1^1^9Sn=6.23σ+94.67, r=0.943。农药的初筛表明, 这些化合物除有很好的杀螨活性外, 还有一定的杀菌, 除草和植物激素作用。

The synthesis of twenty methyldicyclohexyltin aromatoxyacetates from bis(methyl-dicyclohexyltin) oxide and aromatoxyacetic acids is reported. Their characterization by IR, NMR (^1H, ^1^3C, ^1^1^9Sn) is described. These compounds are five coordinate, carboxylate-bridged polymers except the compounds 11 and 12. A good linear relationship is found between the ^1^1^9Sn chemical shifts and the aryl groups. δ^1^1^9Sn=6.23σ+94.67, r=0.943 The results of the preliminary biossay showed that the compounds have b etter antibiotic activities to plant pathagenic fungi, herbicidal and inhibitory activities, especially high acaricidal activity.
