    Description / Table of Contents: Zusammenfassung Kondensation von β-Aroyl-α-[1,3-diphenyl-5(4H)-oxo-pyrazol-4-yl]-propionsäure mit Hydrazinhydrat ergibt 4,5-Dihydro-3(2H)-pyridazinon (2). Reaktion von2 mit POCl3 und P2S5 liefert ein Dichlorderivat (7) und ein Dithion (4). Das Verhalten dieser beiden Verbindungen gegenüber verschiedenen Reagentien wurde untersucht. Antibakterielles screening (in vitro) ergab mäßige Aktivität gegenüber verschiedenen Bakterienstämmen.
    Notes: Summary Condensation of β-aroyl-α-[1,3-diphenyl-5(4H)-oxo-pyrazol-4-yl] propionic acid with hydrazine hydrate affords 4,5-dihydro-3(2H)-pyridazinone (2). Reaction of2 with POCl3 and P2S5 gives a dichloro derivative (7) and a dithione (4). The behavior of the dichloro and dithione derivatives toward various reagents was studied. Thein vitro antibacterial screening reveals moderate activities against certain bacteria.
