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，~（１３）Ｃ，~（１１９）Ｓｎ）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（~（１１９）Ｓｎ）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．
21 mixed trialkyltin carboxylates were synthesized. The structures of the compounds were characterized by IR and 1H NMR spectra (~ 1H, ~ (13) C, ~ (119) Sn) and mass spectra. For the substituted benzoate compounds, the chemical shift δ (~ (119) Sn) of the tin atom has a good linear relationship with the Hammett constant of the substituent on the benzene ring. The bioassay results of the compounds show that they have high acaricidal activity.
