Abstract

New azo- and bisazo-5-pyrazolone dyes have been synthesised by azo coupling of various arylamines and aryl diamines with 5-pyrazolones: 1-methyl-3-phenyl-1 H-pyrazol-5(4 H)-one, 1-(4-chlorophenyl)-3-isopropyl-1 H-pyrazol-5(4 H)-one and 3-isopropyl-1-(4-methoxyphenyl)-1 H-pyrazol-5(4 H)-one, respectively. All new synthesised dyes have been characterised by FTIR, 1H, 13C NMR and UV-Vis spectral studies with GC/MS and LC/MS analyses. FTIR and 1H NMR studies confirmed the existence of azo- and hydrazo-tautomeric forms of the dyes in the solid and liquid states, respectively.
