Copper(II) Fluoride

Copper(II) fluoride is an inorganic salt with the chemical formula CuF 2.

Synthesis
Copper(II) fluoride can be made by heating copper metal and fluorine gas to 400 °C.

Another method of creating it involves mixing a solution of hydrofluoric acid with basic copper(II) carbonate or copper(II) hydroxide.

Reactions
Copper(II) fluoride is used in the fluorination of hydrocarbons. The atmopshere in these reactions must have oxygen and the temperature is at least 400 °C. The largest limitation of this kind of reaction is the product must be able to survive the high temperature necessary for the reaction to take place.

Due to the high temperature, the hydrogen fluoride gas and the copper produced in this reaction will create more copper(II) fluoride.
