Some novel reactions of indole-2,3-dione (1) with pyrazolone (2) under thermal and photochemical conditions have been studied.Under thermal conditions, a variety of novel compounds viz. 1,3-dihydro-3--2H-indol-2-one (3), 3,5-dimethyl-1,7-diphenylspiro-2'-one (4), and 5-fluoro-3,3-bis(3'-methyl-5'-oxo-1'-phenylpyrazol-4'-yl)indol-2-one (5) were obtained.The photochemical irradiation afforded other compounds like 3-methyl-4,5-dioxo-1-phenylpyrazolobenzapine (6), and 3--5-fluoroindol-2-one (7) in addition to thermal products (3) and (4) or (5).
