Abstract

In this research, a series of spiro compounds was efficiently synthesized via one-pot multi component reactions of isatins, aryl amines, dimethyl acetylenedicarboxylate and hydrazine in the presence of Zn(BDC) MOF as catalyst. The key superiority of this process is high yields, easy work-up, short reaction times, and purification of the products by the non-chromatographic system. The study of the reusability of the catalyst showed that the Zn(BDC) can be readily recovered and reused six times with a slight decrease in its activity. Furthermore, the catalyst was characterized by SEM, EDX, FT-IR and XRD analysis.
