The NiCo2O4@Ni(BDC) metal-organic frameworks as a suitable and green catalyst have been developed for the one-pot synthesis of 2,4-diamino-6-arylpyrimidine-5-carbonitrile derivatives. The multi-component reactions of aldehydes, malononitrile and guanidine hydrochloride were efficiently catalyzed using a novel metal-organic framework under reflux conditions. Simple procedures, high yields, short reaction
的镍钴2 ö 4 @Ni(BDC)的金属-有机骨架作为合适的和绿色的催化剂已经开发了用于在一锅合成2,4-二氨基-6-芳基嘧啶-5-甲腈衍生物。醛,丙二腈和盐酸胍的多组分反应使用新型金属有机骨架在回流条件下得到了有效催化。该程序的优点是操作简单,产率高,反应时间短和催化剂的可重复使用性。通过FT-IR,SEM,XRD,EDX,TGA,VSM和TEM分析对催化剂进行了全面表征。
