Synthesis and characterization of ligand diimines n-(1-(propionyloxy) propylidene) benzénamine, n-(2-methyl-1, 4-diphenyl-4-(phenylimino)butylidene) benzenamine and their complexes of copper and zinc

The objective of this study is to synthesize Schiff base ligand, (diimine) N-(1 (propionyloxy)propylidene) benzenamine L1 and N-(2-methyl-1,4-diphenyl-4-(phenylimino) butylidene) benzenamine L2 from precursors propionic anhydride and 1,4-diphenyl-2-methylbutane-1,4-dione successively, and on the other hand their corresponding copper and zinc metal complex (L1)2MCl2 (M = Zn: C1, M = Cu: C2) and (L2)2MCl2 (M = Zn: C3 M=Cu: C4). The compounds thus obtained were characterized by IR spectroscopy, 1H-NMR; 13C-NMR and mass spectrometry.
