摘要/Abstract

摘要： 本文测定了二十个含有烷基、苯基、烯丙基、五元杂环基及其它极性基团的Sn(Ⅳ)化合物的¹¹⁹Sn、¹¹⁷Sn-NMR谱,讨论了各种取代基对Sn核电子云密度及磁屏蔽的影响,考察了¹¹⁹Sn谱峰随溶剂、浓度、温度的变化,研究了Ph₃SnCl化合物与DMSO配位生成配合物的过程,测出了平衡常数和自由能的变化。

关键词: 有机锡化合物, ¹¹⁹Sn、¹¹⁷Sn-NMR谱, 有机锡配合物

Abstract: The ¹¹⁹Sn,¹¹⁷Sn-NMR spectra were recorded for twenty organo-tin (IV) compounds containing alkyl, phenyl, allyl, five-membered heterocyclcs and other polar groups. The substituent influence on tin electron density and magnetic shielding were discussed. The effects of solvents, concentration and temperature on ¹¹⁹Sn resonances were investigated. The complex formation of Ph₃SnCl with DMSO was studied and the equilibrium constant K and △G were calculated.

Key words: Organo-tin compounds, ¹¹⁹Sn.¹¹⁷Sn-NMR spectra, Organotin complex formation
