| 摘 要： | 合成了10个二正丁基锡(IV)基羧酸酯化合物{nBu2Sn (O2CR)]2O}2(A1~A5)和nBu2Sn (O2CR)2(B1~B5)(R=1:CCl3;2:CHCl2;3:CH2Cl;4:PhCH=CH;5:2,2,3,3-四甲基环丙基),其中A4、A5和B5为新化合物,对它们进行了元素分析和IR及、1H、13C、119Sn NMR谱表征,重点讨论了13C和119Sn NMR谱的谱学特征及化学位移值与母体酸的PKa值大小的关系,并在此基础上推测了它们分子结构。

| Abstract: | Ten di-n-butyltin(IV)carboxylates{nBu2Sn(O2CR)]2O}2(A1~A5)and nBu2Sn(O2CR)2(B1~B5)(R=1:CCl3;2:CHCl2;3:CH2Cl;4:PhCH=CH;5:2,2,3,3-tetramethylcyclopropyl) were synthesized. Compounds A4、A5 and B5 are first re-ported. All compounds were characterized by elemental analysis, IR,1H,13C and 119Sn NMR spectra. The spectral featurcs of 13C and 119Sn NMR spectra and the relation between δ(13C or 119Sn)valucs and PKa valucs of the parent acids were disscussed in detail. On this basis, the molecular structures of these compounds were inferred. |
