Trifluoromethyliodine(V) tetrafluoride and related compounds

Abstract

Trifluoromethyl iodide is oxidised by chlorine trifluoride in C₆F₁₄ at –78 °C to give trifluoromethyliodine(V) tetrafluoride. Evidence for the formation of trifluoromethyliodine(III) difluoride has also been obtained. CF₃IF₄ Decomposes readily at 20 °C but is more stable in this respect than CF₃IF₂. Other R_FIF₄[R_F= C₂F₅, (CF₃)₂CF, or n-C₄F₉] compounds are more stable with respect to decomposition than had been supposed. CF₃IF₄ Reacts with methylmethoxosilanes at 20 °C to give CF₃IF_4–n(OMe)_n(n= 1–4).
