m-Dinitrobenzene and derivatives react with nitromethane or some other primary nitroalkanes in the presence of lithium tert-butoxide in 1,3-dimethyl-2-imidazolizinone (DMI) at room temperature, giving the corresponding 4-nitromethyl and 4-[1-(hydroxyimino)alkyl] derivatives, respectively, in moderate yields. These products are smoothly converted to the corresponding carbonyl compounds by oxidative
米-Dinitrobenzene和衍生物与硝基甲烷或在锂存在其他一些初级硝基烷反应,叔丁醇中在室温下的1,3-二甲基-2- imidazolizinone(DMI),得到相应的4-硝基和4- [1- (羟基亚氨基)烷基]衍生物分别以适中的产率。使用臭氧化的氧通过氧化Nef反应将这些产物平稳地转化为相应的羰基化合物。
