| Abstract | ||
| In this study, some of the new compounds have been synthesized including some of different Schiff bases (1-6) via the reaction of phenyl-1,4-diamine with substituted benzaldehyde in absolute ethanol and converted into derivatives of 1,3-oxazepine-4,7-dione (7-12) via ring closure reaction [2+5] of Schiff bases with maleic anhydride in dry benzene then the 1, 3- oxazepine -4, 7- compounds (7-12) were reacted with phenylhydrazine to produce 1,3-diazepine-4,7-dione (13-18). The prepared compounds were characterized by determination of melting point, FT-IR and UV-Visspectra, and some of the prepared compounds have been characterized by (1H-NMR& C.H.N.) techniques. | ||
