Heptafluoroisopropyl iodide Usage And Synthesis

Chemical Properties

clear colorless to yellowish liquid

Uses

Heptafluoro-2-iodopropane may be used in the preparation of perfluoropropyl magnesium bromide and perfluoropropyl magnesium iodide. It may be used as chain-transfer agent in telomerization reactions of:

  • 1,1-difluoroethylene and tetrafluoroethylene
  • CF3I, C2F5I and n-C3F7I with 1,1-difluoroethylene
  • n-C3F7I with tetrafluoroethylene

General Description

Heptafluoro-2-iodopropane is a secondary fluoro alkyl iodide. It can be prepared by addition of iodine monofluoride to hexafluoropropene.

Flammability and Explosibility

Non flammable

Purification Methods

Purify it by gas chromatography on a triacetin (glyceryl triacetate) column, followed by bulb-to-bulb distillation at low temperature. Store it over Cu powder to stabilise it. UV has max at 271nm ( 240) in pet ether (b 60-80o). [Haszeldine J Chem Soc 1767, 3761 1953, Beilstein 1 III 255, 1 IV 225.]
