Diiodine oxide, also known asiodo hypoiodite, is anoxide of iodine that is equivalent to an acid anhydride ofhypoiodous acid. This substance is unstable and it is very difficult to isolate.[2]
Diiodine oxide can be prepared by reacting iodine withpotassium iodate (KIO3) in 96%sulfuric acid and then extracting it into chlorinated solvents.[2]
Diiodine oxide reacts with water to formhypoiodous acid:
