An efficient and recyclable nanocatalyst for the green and rapid synthesis of biologically active polysubstituted pyrroles and 1,2,4,5-tetrasubstituted imidazole derivatives

Abstract

So the use of Fe₃O₄@SiO₂–ZrCl₂-MNPs leads to an improved protocol in terms of the compatibility with the environment, yields of the products, reaction times and the amount of the catalyst when compared with other catalysts.
