The structures of the products were characterized by their physical properties, comparison with authentic samples and IR, 1 H NMR and 13 C NMR spectroscopy. Easy preparation of the catalyst, mild reaction conditions, easy work-up procedure, excellent yields and short reaction times are some of the advantages of this work.
