摘要: 合成了21个混合三烃基锡羧酸酯。利用红外光谱、核磁共振谱(1H,13C,119Sn)和质谱表征了化合物的结构。对取代苯甲酸酯化合物,锡原子的化学位移δ(119Sn)与苯环上取代基的Hammett常数有很好的线性关系。化合物的生物活性测定结果表明,它们具有高效杀螨活性。

Abstract: Twenty-one butyldicyclohexyltin carboxylates were prepared and their structures were characterized through IR, NMR(1H, 13C, 119Sn) and MS. For the arylcarboxylates, there is a good linear relationship between the chemical shift of 119Sn and the Hammett constant of the substituent.The results of the biological test showed that the compounds have a good acaricidal activity.

Key words: Mixed trialkyltin carboxylate, Chemical shift of 119Sn, Biological activity
