摘　　要：合成了７种三苯基锡Ｎ－亚水杨基氨基酸酯，通过元素分析、ＩＲ、ＵＶ、１ＨＮＭＲ和１３ＣＮＭＲ测定，对其结构进行了表征。结果表明，合成的化合物具有醇亚胺和酮胺互变异构体结构，锡原子是五配位的，存在着分子间酚羟基（酮羰基）氧原子同锡原子的配键。测定了具有光学活性化合物的比旋光度。Seven novel compounds of triphenyltin N salicylideneamino carboxylates were synthesized. The structures of the compounds were characterized by elementary analysis, UV, IR, 1H NMR and 13 C NMR. The results of the studies indicate that the tautomeric equilibrium between the “enol imine” and “keto enamine” exists in the compounds. The compounds are phenolic (ketonic) oxygen atom bridged polymers containing five coordinated tin atom.
