Fluorodiiodomethane
Fluorodiiodomethane is a trihalomethane with the chemical formula.
Synthesis
Fluorodiiodomethane can be obtained by the Finkenstein reaction of dibromofluoromethane with sodium iodide in acetone.Also, iodoform reacts with mercuric fluoride at 120 °C to afford fluorodiiodomethane after distillation. This reaction is used to prepare large quantities of the reagent.
Chemical properties
It is a highly efficient precursor of fluorocarbenes. The compound can generate fluorocarbenes that react with alkenes to give compounds containing fluorinated three-membered rings.It is also a reagent for monofluorocyclopropanation.
