摘　　要：合成了１６个β－烷氧羰基乙基三氯化锡与二甲基亚砜、Ｎ－氧化吡啶、吡啶等单齿配体的配合物，经过元素分析、ＩＲ、＾１Ｈ ＮＭＲ、ＴＧ－ＤＴＡ等表征了其结构。报道了β－烷氧羰基乙基三氯化锡配合物和醇的酯交换反应，提出了其可能的反应机理。Sixteen complexes of β - alkoxycarbonylethyltintrichlorides with monodentate ligands such as dimethylsulfoxide, pyridineN - oxide and pyridine were synthesized and characterized by elemental analysis, IR, 1H NMR and TG - DTA. The transesterification of β -methoxycarbonylethyltin trichloride complexes with an alcohol was reported and the possible mechanism was suggested.
