6-Chloro-and 7-chloro-5, 8-quinolinequinone (II and III) were prepared and aryl groups were introduced at the unsub-stituted positions of the quinone rings by reaction with diazonium salts; alkyl groups were introduced by peroxide alkylation. The 7-aryl-6-chloro-and 6-aryl-7-chloro-5, 8-quinolinequiuones were readily hydrolyzed to the corresponding hydroxyl derivatives. The parent compound, 5, 8-quinolinequinone, adds hydrogen chloride at the 6, 8-positions exclusively to yield 6-chloro-5, 8-dihydroxyquinoline under anhydrous conditions.Several of thederivatives of 5, 8-quinolinequi-none2 described in precedingpapers ofthis series have displayedsignificant amebicidal activity in preliminary tests. One of the most effective of these was 7-undecyl-6-hydroxy-5, 8-quinolinequi-none (I). 3 Since the well-known amebicides-orm and Diodoquin are halogenated quinolines, it was of interest to investigate the activity of
