Abstract: Bu çalışmada, bazı anilin türevleri diazolanmış ve 3-aminokrotononitril ile kenetlenerek 2-arilhidrazon-3-ketiminokrotononitril bileşikleri elde edilmiştir. Elde edilen 2-arilhidrazon- 3-ketiminokrotononitril bileşikleri, hidrazin monahidrat ile reaksiyona sokularak bir seri 5-amino-4-arilazo-3-metil-1-fenil-pirazol türevleri sentezlenmiştir. Elde edilen bileşikler, hidroksilamin ile reaksiyona sokularak bir seri disazo -5-hidroksi-3-metilisoksazol türevleri sentezlenmiştir. Elde edilen bu disazo boyarmaddeleri FT-IR, 1H-NMR ve element analizi gibi spektral yöntemlerle karakterize edilmiş ve görünür bölge absorpsiyon spektrumları üzerine değişik çözücü, asit-baz ve sübstitüent etkisi incelenmiştir. Böylece hem diazo hem de kenetlenme bileşeni heterosiklik olan yeni disazo boyarmaddeler sentezlenmiştir. In this study, some aniline derivatives were diazotised and coupled with 3-aminocrotononitrile to give 2-arylhydrazone-3-ketiminocrotononitriles. 2-arylhydrazone- 3-ketiminocrotononitriles were then reacted with hydrazine monohydrate to give 5-amino-4- arylazo-3-methyl-1-phenyl-pyrazole derivatives. The synthesized components were then reacted with hydroxylamine to give -5-hydroxy-3-methyl isoxazole derivatives. The synthesized disazo dyes were characterized by elemental analysis and spectral methods such as FT-IR and 1H-NMR. The effect of varying solvent, acid-base and substituent upon the absorption ability of dyes was examined. Thus, disazo dyes were synthesized which is containing heterocyclic cycles both the diazo and coupling components.
