Substituted pyrroles are an essential class of heterocyclic compounds. In this research, an efficient and eco-friendly method has been developed for the synthesis of pyrrole derivatives from the reaction of 2,5-hexanedione and primary amines. Magnetic nanoparticles supported on functionalized. 7-aminonaphthalene-1,3-disulfonic acid-functionalized. silica (Fe3O4@SiO2@Propyl–ANDSA) has been inves...
