FIVE-MEMBERED 2,3-DIOXOHETEROCYCLES. XXIII. SYNTHESIS OF 1-ARYL-3-AROYL-4,5-DIHYDRO-4,5-PYRAZOLEDIONES AND THEIR REACTION WITH WATER AND ALCOHOLS

4-Aroyl-3-arylhydrazono-2,4-dioxobutyric acids were obtained by the azo coupling of aroylpyruvic acids with arenediazonium salts. Under the influence of thionyl chloride (benzene, 78 deg C, 1.5-4h) they undergo cyclization to 1-aryl-3-aroyl-4,5-dihydro-4,
