| Abstract This research includes the preparation and characterization of a number of heterocyclic compounds of the following types: . Penta-heterocyclic rings. . Hexa-heterocyclic rings. . Seven-heterocyclic rings. Where she attended these compounds article Thiocarbohydrazide (1), through conversion of Thiocarbohydrazide to hydrazones (2,3,4) of reaction with compound carbonyl (benzaldehyde, 4- chlorobenzaldehyde, acetophenone) and then reactance hydrazones with sodium azide to prepare compounds tetrazole (5), or with Anthranilic acid (2- amino benzoic acid ) for preparation of compounds quinazole (6), or reaction with anhydrous acid (maleic anhydride, phthalic anhydride) for the purpose of preparing Oxazepine (7) (8). Characterization of the synthesized compounds were established by infrared spectra, and NMR spectra 1 H{13C}N.M.R & 13C{1H}N.M.R | ||
