Iodine pentafluoride, IF5, is a fluoride of iodine. It is a colourless or yellow liquid with a density of 3250 kg m−3. It was first synthesized by Henri Moissan in 1891 by burning solid iodine in fluorine gas.[2] This exothermic reaction is still used to produce iodine pentafluoride, although the reaction conditions have been improved.[3][4]
I2 + 5 F2 → 2 IF5
Chemistry
Iodine pentafluoride is a strong fluorination agent and is highly oxidative. It reacts vigorously with water forming hydrofluoric acid.
Primary amines react with iodine pentafluoride forming nitriles after hydrolysis with water.[5]
R-CH2-NH2 → R-CN
