摘要: 测定了15种三(2-甲基-2-苯基同基)锡苯氧乙酸酯化合物的13C NMR谱,利用模型化合物对比及化学位移计算比较等方法,对全部谱线进行了归属.讨论了化合物13C NMR谱与结构的关系,求得对苯环碳的取代基化学位移参数(SCS):Cipso=30.0,Cortho=-13.8,Cmeta=0.8,Cpara=-7.5.

关键词: 13C NMR, 三(2-甲基-2-苯基丙基)锡苯氧乙酸酯, 取代基化学位移值

Abstract: The 13C NMR spectra of fifteen new tris(2-methyl-2-phenyl propyl) tin aryloxyacetates were recorded.The chemical shifts of various carbon resonances have been assigned on the basis of calculation and comparison with the chemical shifts of the model compounds.The data of the effect of substituent of on the 13C chemical shifts in benzene ring were obtained:Cispo=30.0,Cortho=-13.8,Cmeta=0.8,Cpara=-7.5.

Key words: 13C NMR spectra, Tris(2-methyl-2-phenyl propyl) tin aryloxyacetate, Substituent effect
