This work involves the synthesis of different substituted amino-chalcones via claisen- schmidt condensation reaction between p-amino acetophenone and different aromatic substituted benzaldehydes. The second step involves the conversion of amino-chalcones to diazonium salt which were reacted with different phenolic compounds to give azo-chalcone . Some azo-chalcones containing acetyl group wrer prepared by reactingdiazonium salt with para-hydroxyacetophenone, and this gave bis- azo-chalcoe on reaction with substituted aromatic benzaldehyde.
The chemical structure of the synthesized compounds were confirmed on the basis of their spectral data (FTIR, 1HNMR, 13CNMR) and CHN analysis.
