Diiodine oxide, also known as iodohypoiodite, is an oxide of iodine that is equivalent to an acid anhydride of hypoiodous acid. This substance is unstable and it is very difficult to isolate.[2]
Preparation
Diiodine oxide can be prepared in 96% sulfuric acid and extracted into chlorinated solvents.[2]
Reaction
Diiodine oxide reacts with water to form hypoiodous acid:
- I2O + H2O → 2 HIO
