摘要
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。
The 13C- NMR spectra were recorded for eighteen organotin ( Ⅳ) compounds containing alkyl, phenyl, allyl, five-membercd hclcrorings and other polar groups. All the 13C spectral lines were asslgned. The Sn - C bond property in alkyl and phenyl us cempouds. and the influcncc of polar substitucnts on C- 1 αvalues are Jiscassed.The rnagmtudes and orders of carbon-tin coupling constants nJc-Sn and the rel,ationship between and were also investigated.
