Abstract

Acetylacetone and malononitrile were coupled with diazotized arylamines to give arylazoacetylacetones and arylazomalononitriles. When refluxed with 3-hydrazino-4,5-diphenyl-1H-pyrazolo[3,4-c]pyridazine in the presence of ethanol/HCl they yielded the corresponding 3-[4-(arylazo)-3,5-dimethylpyrazol-1-yl]- and 3-[3,5-diamino-4-(arylazo)pyrazol-1-yl]-4,5diphenyl-1H-pyrazolo[3,4-c]pyridazine dyes. The dyes were applied to polyester and polyamide fabrics, their spectral and fastness properties were measured.
