Synthesis of some substituted pyrazolones

Ethyl-2-[diazo (substituted benzene)] acetoacetates II were treated with thiosemicarbazide to furnish 4-(substituted phenyl) azo-5-methyl-2-thioamido-3- pyrazolones III. Compounds II on treatment with one molar quantity of thiocarbohydrazide (TCH) yielded 4-(substituted phenyl) azo-5-methyl-2- thiocarboxyhydrazino-3-pyrazolones IV whereas bis-2-[4-(substituted phenyl) azo-5-methyl-3-pyrazolone] thioketones V were obtained by treating II with two molar quantity of TCH. All the final desired compounds have been synthesized by microwave irradiation technique as well as classical thermal method. The structures of the newly synthesized compounds have been established by analytical and spectral methods.
