The Ullmann condensation of o-bromophenol and 5-bromo-6-hydroxyquinoline gave diphenylene dioxide (III), 5, 6-phenylenedioxyquinoline (IV), and diquinoline 5, 6-dioxide (V). Of these products, (IV), colorless needles, m. p. 127-129°, is a new compound unknown to date in literature. The melting point of the pure diquinoline 5, 6-dioxide previously given was found to have been an error and it should be 317°.
