Yellow liquid

Iodine pentafluoride Basic information

    Iodine pentafluoride (IF5) is a colorless to pale yellow fuming liquid with a pungent odor.   The highly reactive IF5 (melting point 9.4 °C) is distillable at 100.5 °C without any decomposition.   Decomposition commences at temperatures above 400 °C.
    Iodine pentafluoride has good thermal stability and is the most stable halogen compound.   The reactivity of IF5 is much weaker than that of other halogen compounds, and it does not interact with silicon, magnesium, copper, iron, and chromium at room temperature, and only interacts with molybdenum, tungsten, phosphorus, arsenic, antimony, boron, etc.
    It is the least reactive of the halogen fluorides and classified as a soft fluorinating reagent.   It is used as a mildest, selective fluorinating reagent in the fluorination of organic molecules.

Iodine pentafluoride is a fluorinating agent and strong oxidant, which plays an important role in organic synthesis. It can be used to prepare pentafluoroiodoethane:
5 CF2=CF2 + IF5 + 2 I2 → 5 C2F5I
In addition, iodine pentafluoride can also react with isothiocyanato to generate fluorinated hydrocarbon derivatives, and to synthesize other fluorine-containing compounds.
Iodine pentafluoride (IF5) is rarely used to fluoride common organic compounds due to the difficulty in controlling their reactivity.
