Abstract
Number of new derivatives of 1,3-oxazepinewere synthesized by cycloaddition reaction (2+5) of ( NE,N'E )-4,4'-methylenebis (3-chloro-N-(4-halobenzylidene)aniline) with exo-3,6-epoxy-1,2,3,6-tetrahydrophthallic anhydride, tetrachlorophthalic anhydride and citraconic anhydride by refluxing in dry benzene. ( NE, N'E )-4,4'-Methylenebis(3-chloro-N-(4-halobenzylidene)anilines)were prepared by thermal condensation of 4,4'-Methylenebis(3-chloroaniline) and p-halobenzaldehydes in absolute ethanol under reflux conditions. The structure of the target compounds were characterized by their spectral data of FT-IR and 1 H-NMR. Keywords : Azomethines, Carboxylic Acid Anhydrides , 1, 3-Oxazepine .
