Özet
In this study, 20 novel disazo dyes containing pyrazole derivatives were synthesized by a convenient method. Diazotized aniline and some aniline derivatives were reacted with malononitrile to give 2-arylazomalononitrile derivatives 1 (ae). The synthesized 2-arylazomalononitrile derivatives were reacted with hydrazine and phenyl hydrazine to afford the corresponding 3, 5-diamino-4-arylazo-1H-pyrazole 2 (ae) and 3, 5-diamino-4-arylazo-1-phenylpyrazole 3 (ae). Diazotized compounds of 2 (ae) and 3 (ae) reacted with ethylacetoacetate to give 4-arylazo-3-amino-1H-pyrazole-5-ylazo-ethylacetoacetate 4 (ae) and 4-arylazo-3-amino-1-phenylpyrazole-5-ylazo-ethylacetoacetate 7 (ae). The obtained 4 (ae) and 7 (ae) were reacted with hydrazine and phenyl hydrazine to give disazo dyes 5 (ae), 6 (ae), 8 (ae) and 9 (ae), respectively. The synthesized disazo dyes were characterized by spectroscopic techniques as well …
