Substitution reactions of iodine pentafluoride: preparation and properties of methoxoiodine(V) fluorides

Abstract

Methoxoiodine(V) fluorides, IF_{5 –n}(OMe)_n(n=1–4), and fluoro(methyl)silanes are formed from reactions of iodine pentafluoride with methoxomethylsilanes at 20 °C. The IF₅ derivatives are labile and readily decompose with reduction of iodine(V). Although Me₃SiF is formed from reactions of IF₅ with other Me₃SiX [X = Cl, SMe, OC(O)R, or Me] compounds, substituted derivatives of IF₅ are not isolated because reduction occurs.
