Novel azo dyes derived from 8-methyl-4-hydroxyl-2-quinolone: Synthesis, UV-vis studies and biological activity
In this study, N,N′-di-(2-methylphenyl)malonamide was synthesized and reacted with polyphosphoric acid to afford 8-methyl-4-hydroxyl-2-quinolone. Eight novel azo disperse dyes were then synthesized by linking diazotized p-substituted aniline derivatives w
