Quinonedichlorodiimide (I) reacts with chinoform (5-chloro-7-iodo-8-hydroxyquinoline (II)) as well as with 7-iodo-8-hydroxyquinoline-5-sulfonic acid (III) to yield a colored compound. The chemical structure of this compound is investigated from the spectral (infrared, ultraviolet, nuclear magnetic resonance, Mass) data and the elemental analysis. The fact that both the reactions of I+II and I+III give the same compound suggests that I replaces chlorine atom and sulfonic acid group at 5-positions of II and III, respectively. The spectral data supports that the reaction product is 5-qunionediimino-7-iodo-8-hydroxyquinoline.
