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]

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
