本文从反应历程入手,研究了~(13)C—NMR谱的化学位移与芳烃亲核取代位置选择以及反应活性的关系,文章指出在加成—消去历程的亲核取代反应中,可根据~(13)C—NMR谱化学位移值的估算推出芳烃亲核取代发生的位置和反应活性顺序,并对一些不符合规律的例外作出了分析。
In this paper, the chemical reaction of ~ (13) C-NMR spectroscopy was studied in terms of the reaction process. The relationship between the chemical shifts and the nucleophilic substitution positions of aromatics and their reactivity were also studied. In the nucleophilic substitution reaction of addition- (13) Estimation of chemical shift values by C-NMR spectroscopy The position of the nucleophilic substitution of aromatics and the order of reactivity were deduced and some irregularities were analyzed.
