Synthesis of new Azo compounds combining with heterocyclic groups

Six compounds of Azo containing heterocyclic groups, as derivatives for α, β- unsaturated ketones (the chalcones analogs), were synthesized. The Azo compounds combining the α, β- unsaturated ketones were prepared by the reaction the diazonium salt with an aryl carbonyl compound, such as benzaldehyde, 2-chlorobenzaldehyde, and furfual. And then treated with acetone. The products were reacted with benzil to prepare two chalcone groups. The results were reacted with NH2OH.HC/EtOH and glacial HAC, as a catalyst. Several derivatives of azo compounds that containing heterocyclic group were syntheside. The newly synthesized compounds have been diagnosed by (FTIR, 1H NMR, 13CNMR, and MASS) spectroscopy.
