A simple, rapid, and highly efficient method has been developed for the aza-Michael addition of acrylonitrile to 2-aryl-oxymethylbenzimidazole derivatives in the presence of anhydrous potassium carbonate under microwave irradiation. A series novel of 1-cyanoethyl-2-aryloxymethylbenzimidazole derivatives have been prepared and characterised by 1H NMR, 13C NMR, IR spectra and elemental analysis.
在微波辐照下,在无水碳酸钾存在下,开发了一种简单、快速、高效的方法,用于丙烯腈与 2-芳基氧甲基苯并咪唑衍生物的偶氮-迈克尔加成反应。制备了一系列新型 1-氰乙基-2-芳氧基甲基苯并咪唑衍生物,并通过 1H NMR、13C NMR、IR 光谱和元素分析进行了表征。
