摘要: 测定了33个三环己基脂肪族和芳香族羧酸锡在非配位溶剂(CDCl3)中的13C和119Sn NMR谱。结果表明:化学位移δ(119Sn)值主要由锡原子的配位数决定,结构上微小的变化。都能在δ(119Sn)值上明显地表现出来。讨论了不同类型化合物间NMR参数间的关系。

Abstract: The 13C and 119Sn NMR spectra of CDCl3 solutions of aliphatic and aromatic tricyclohexyltin (IV) carboxylates have been recorded. The chemical shifts (δ119Sn) and the coupling constants 1J (13C, 119Sn) depend markedly on the coordination number of the tin atom. The chemical shifts and coupling constants 1J (13C,119Sn) for aliphatic tricyclohexyltin (IV) carboxylates are in the range 6-11 ppm and 341-345 Hz, for aromatic tricyclohexyltin (IV) carboxylates are in the range 10 to 40 ppm and 310-340Hz, which provide evidence that the compounds are monomeric species in the solutions irrespective of their structure in the solid state.
