Production

Pentafluoroethyl iodide can be produced by electrochemical fluorination of 1,1,2,2-tetrafluoro-1,2-diiodoethane.^[3]

2 C₂F₄I₂ + 2 HF → C₂F₅I + I₂ + H₂

It can also be produced by react tetrafluoroethylene, iodine and iodine pentafluoride.^[4]

5 C₂F₄ + 2 I₂ + IF₅ → 5 C₂F₅I

Properties

Pentafluoroethyl iodide is a pungent colourless gas^[1] and an anesthetic.^[5][6]

Uses

Pentafluoroethyl iodide is an intermediate of preparing other compounds.^[7][8][9]
