| 摘 要： | 用400MHz超导核磁共振波谱仪测定了X取代苯甲酰苯胺(X=p-NO2,p-Cl,p-Br,p-1,H,p-CH3,p-OCH3,m-CH3)的1H和13C NMR谱,按双参数方程进行计算,结果表明N-1H,羰基碳,与羰基相连的苯环碳和与氮相连的苯环碳等碳原子的化学位移与取代基共轭效应参数σR和诱导效应参数σI间的良好的线性关系。测得了双参数方程中适用于苯甲酰苯胺衍生物的3个常数a、b和c的值以及σR、σI的权重。

| Abstract: | The 1H and 13C NMR spectra for a series of X-substituted benzanilide were obtained and analyzed on the basis of dual parameter equation. The three constants in the equation were determined. The relative importance of resonance effect and field effect were calculated. It was found that the linear correlation between the chemical shifts of N-1H、C1、C2、C3、C6 and substituent effect σR、σI was good straight line. |
