Synthesis and dyeing properties of a new class of condensed carbocyclic arylazopyrazolo[1,5‐a] pyrimidines

Abstract

Several new condensed carbocyclic arylazopyrazolo[1,5‐a]pyrimidine derivatives were obtained from 4‐arylazo‐3,5‐diaminopyrazoles as starting components. The application and dye characteristics for the synthesized dyes are demonstrated.
