| Objective: The aim of the work was to designed and synthesized novel heterocyclic tetrakisazo dyes.Methods: 2, 2'[(4, 4'-dihydrazonebiphenyl)]-bis (3-iminobuthyronitrile)(1) were synthesized by diazotization of benzidine using hydrochloric acid in water. Compounds (1) reacted with hydrazine hydrate to afford the corresponding 4, 4'-bis [3-methyl-5-amino-1-H-pyrazol-4-ylazo] biphenyl (2). Seven novel hetaryltetrakisazobenzidine Derivatives 3 (ag) were achieved by diazotization of 4, 4'-bis [3-methyl-5-amino-1-H-pyrazol-4-ylazo] biphenyl and coupling with various coupling components.Results: The obtained hetaryltetrakisazo dyes 3 (ag) were characterized based on FT-IR, 1Conclusion: Synthesis and characterization of seven of these nine novel compounds synthesized, which are hetaryltetrakisazo dyes 3 (ag). |
