Synthesis of azo- Schiff base and azo-oxazepine compounds from nucleus of 2,6-diaminopyridine by using Microwave Irradiation

Abstract

Some new azo-schiff bases were prepared by reacting aromatic diazonium salts with aromatic Schiff bases .azo-oxazepine was prepared from the latter comounds via cycloaddition reaction with maleic anhydride using the enviorement friendly microwave technique as a participation to the applications of green chemistry .Spectroscopic methods (IR, 1HNMR) as well as some physical properties were used for the structural elucidation of the prepared compounds.
