Synthesis and Characterization of Heterocyclic Compounds Derived From Diimine

Abstract

The target of present work involves the creating of new imines derived from selected di amines after connecting five membered heterocyclic rings of the type dithiazole and dioxazole to the parent molecules via the reaction of the previous diamines with chloroacetyl chloride giving the corresponding amides (A1-A3) , then subsequent reaction of the later with thiourea and urea give substantially new dithiazol (th1-th3) and dioxazole (Ox1-Ox3) respective- Part two : Group 1: Synthesis of new derivatives of the diimines (Im1- Im20) by reaction of the diamine with different aromatic aldehyde. Group 2: Synthesis of new derivatives of the azetidine-2-one (az1- az5) by reaction of the diimines with chloroacetyl chloride in benzene. Group 3:Synthesis of new derivatives of the oxazolidine-5-one (oxa1- oxa 6) by reaction of the diimines with trichloroacetic acid in benzene. Group 4: Synthesis of new derivatives of the Imidazolidine-4-one (I1-I6) by reaction of the diimines with glycine in benzene. Group 5: Synthesis of new derivatives of the 1,2,4-triazole (tr1-tr6) by reaction of the diimines with thiosemicarbazide in benzene. Group 6:Synthesis of new derivatives of the pyrimidinon-4-one (P1-P6) by reaction of the di imines with β-alanine in THF. Group 7: Synthesis of new derivatives of the 1,3-Oxazepine and 1,3- Oxazepane (O1-O15) by reaction of the diimines with some acid anhydride , such as (3-Nitrophthalic anhydride, Citraconic anhydride and Phenylsuccinic anhydride) respectively in benzene Part three : Synthesis of new complexes for N,N'-(thiobis (4,1- phenylene)) bis (1-phenylmethanimine) substituted ligands with Fe3+ All prepared compounds were spectrally identified by infrared spectroscopy, UV-Visble spectrum, mass spectrometry, 1H-NMR and 13C-NMR. The results confirmed the validity of the proposed chemical structures.
