Microwave Synthesis of some new compounds 1,3 – Oxazepine – 4 , 7 - dione,derivatives from Schiff bases

The microwave technique is a new method for synthesis of organic compounds, which take a pure and high percent of products and completed with short time, compared with conventional method (heating method). the prepared schiff bases allowed to react by microwave technique which is a new apparatus for synthesis the organic compounds, reacts with malic anhydride to yield (1, 3, 6, 7) 1,3 – oxazepine compounds and reacted with phthalic anhydrides to yield (2, 4, 5, 8) 1,3 – oxazepine compounds. the useful thing in microwave technique is using without solvent there for it called (dry method). the synthesized compounds were identified using melting point apparatus, infrared spectroscopy
