摘要：

Interaction of 4 arylhydrazono-3-methyl-2-pyrazolin-5-ones (1) with acetic anhydride, formaldehyde and formaldehyde/sec, amines afforded derivatives (2), while condensation with benzenesulphonyl chloride gave derivatives 3. The phenylsulphonyl radical in 3 was readily eliminated upon treatment with alcoholic potassium hydroxide to give 1. The structures of these compounds were established by analytical and spectral methods.
