  • Reaction of 3-alkylidene-2,4-pentanediones(1) with arylhydrazines in methanol afforded 4-acetyl-(2), 4-(1-methoxyalkyl)-(3), or 4-vinylpyrazole derivatives(4). 3-(2,2,2-Trichloroethylidene)-2,4-pentanedione(9) reacted with arylhydrazines to give 4-acetyl-1-aryl-3-methylpyrazoles(11). Possible mechanisms for these reactions were proposed.
