本文合成了七个三苄基锡二硫代磷酸酯和八个三[(甲基二苯硅基)亚甲基]锡二硫代磷酸酯, 测定了它们的IR, 1H, 119Sn和31P NMR, 119Sn NMR的化学位移与磷酸酯基的芳环对位取代基Hammett常数呈线性关系。表明该两类化合物均为四价锡的单分子有机锡化合物。

Seven tribenzyltin dithiophosphates and tri[(methyldiphenylsilyl)methylene] tin dithiophosphates were synthesized .the IR, 1H, 119Sn and 31P NMR were studied. the results have shown that there are two liner relationships between chemical shift 119Sn and hammett constant of the para-substituent of the aryl groups on the dithiophosphates of the wto kinds compounds:&119Sn(CH2)=11.55σ+7.38 γ=0.988; &119Sn(Ph2MesSlCH2)=123.89σ+19.75 γ=0.986; A;; spectradata also have shown that they are four-coordination compounds.
