In our research on study chemical reaction of active methylene compounds and brom-acetophenone. Because of brom-acetophenone is compound that contain carbonyl and halogen ,which will take place electrophilic substitution and nucleophilic addition. When active methylene compounds are ethyl acetoacetate and β-diketone, controlling reaction condition, we have found that mono-substitution's production and di-substitution's. production is isolated; active methylene compounds are acetoacetanilide and acetoacetanilide derivate, pyrrolidin-2-one derivants were obtained by substitution and close-ring reaction .but there is no report about it.
本文是让活泼亚甲基类化合物与溴代苯乙酮发生化学反应,由于溴代苯乙酮是含有羰基的卤代烃结构,它可以发生亲电取代和亲核加成反应,当活泼亚甲基类化合物为乙酰乙酸乙酯和β-二酮时,控制反应条件可以发生单取代和双取代两种产物;当活泼亚甲基类化合物为乙酰乙酰芳胺类化合物来反应时,溴代苯乙酮中的羰基与氨基会发生分子内的关环反应生成吡咯烷-2-酮衍生物,这在以前的研究中是没有发现的。

By applying density functional theory, the relationships between the electron structures and the complexation of the two types of bis-β-diketone ligands (dithiol-γ-linked or alkyl-γ-linked) were investigated, based on the polarized continuum model of the self-consistent reaction field. Using the model B3LYP/6-31G**, the geometries of the ligands were optimized and the electron structure changes calculated.
