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.
