A multicomponent one-pot reaction of aromatic aldehyde, malononitrile, and nitromethane is carried out in the presence of HTs (different Mg/Al ratios) and other solid bases, where 2-amino-5-nitro-4,6-diphenylcyclohex-1-ene-1,3,3-tricarbonitriles are obtained. HT with Mg/Al = 5 is the best catalyst for the reaction. The reaction gives best results under solvent-free condition. The catalyst can be easily
芳族醛,丙二腈和硝基甲烷的多组分一锅反应在HTs(不同的Mg / Al比)和其他固体碱(其中2-amino-5-nitro-4,6-diphenylcyclohex-1)存在的情况下进行得到-烯-1,3,3-三腈。Mg / Al = 5的HT是反应的最佳催化剂。在无溶剂条件下,该反应可获得最佳结果。该催化剂可以容易地分离并且是可回收的。其他参数进行了优化。
