本文测定了18个含有各种烷基、苯基、烯丙基、五元杂环及其它极性基团的有机锡化合物的~(13)C—NMR谱。对全部谱线进行了归属。讨论了烷基锡、苯基锡中Sn—C键的性质和极性取代基对C—1δ值的影响。考察了各类C-Sn偶合常数大小顺序,以及~1J_(C-)~(119)Sn与~1J_(C-)~(117)Sn的关系。
In this paper, ~ (13) C-NMR spectra of 18 organotin compounds containing various alkyl, phenyl, allyl, five-membered heterocyclic rings and other polar groups were determined. Attribution to all spectral lines. The properties of Sn-C bond in alkyltin and phenyl tin and the effect of polar substituents on C-1δvalue were discussed. The order of C-Sn coupling constants and the relationship between ~ 1J_ (C-) ~ (119) Sn and ~ 1J_ (C-) ~ (117) Sn were investigated.
