摘    要:
在电子转移停流注射法中通过电子转移,1 芘胺,N 甲基对茴香胺与较稳定的阳离子自由基反应生成活泼的阳离子自由基并偶合.用密度泛函理论(DFT)B3LYP方法,在6 31G 基组下,计算研究了中间产物的几何构型和热力学性质,通过反应过程的能量变化及电荷布居分析推测出其偶合机理.并用电喷雾质谱法检测其偶合产物,实验结果与推测值吻合.

关 键 词:自由基  偶合机理  B3LYP  电喷雾质谱

Abstract:
Using an electron transfer stopped-flow method,the reactions of short-lived 1-aminopyrene and N-methyl-p-anisidine cation radicals,which were formed via the electron transfer reactions with stable cation radicals,were analysed.Dimerization mechanisms about those compounds are studied by density functional theory (DFT) at B3LYP/6-31G~* level,and any possible types of dimerization processes are established and are calculated.The results about equilibrium geometries,the population regularities of the atomic net charges and thermodynamics energies of these compounds show that mechanisms are in accordance with the experiment.The dimmer compounds were analysed by using ESI-MS to confirm the structures.
Keywords:radical  dimerization reaction  B3L YP  ESI-MS
