Applications

Cathodes in nonaqueous galvanic cells, high temp. fluorinating agent.Copper(II) fluoride is used in the preparation of fluorobenzene by reacting with benzene. It is also used in galvanic cells, high-temperature fluorinating agent and fluxing iron castings. Further, it is used as an efficient catalyst in Chan-Lam-Evans coupling reaction to synthesis the diaryl- ether compounds.
