Abstract
A general and efficient onepot protocol has been developed for the synthesis of benzimidazoles and pyrimidinesusing Zn and [email protected] Fe3O4as a heterogeneous catalyst. The prepared catalyst provided good yields of the corresponding products within a short reaction time.Catalyst was characterized by using XRD, TEM, FEG-SEM, EDS, XPS, Raman, CHNS and FT-IR. The present method provided high yields of the products with wide substrates scope.The catalyst could be reused five cycles without a significant loss of catalytic activity.
