Copper(I) fluoride or cuprous fluoride is an

electronegative that it will always oxidise copper to its +2 oxidation state.[5] Complexes of CuF such as [(Ph3P)3CuF] are, however, known and well characterised.[6]

Synthesis and reactivity

Unlike other copper(I) halides like

disproportionate into copper(II) fluoride and copper in a one-to-one ratio at ambient conditions, unless it is stabilised through complexation as in the example of [Cu(N2)F].[7]

2CuF → Cu + CuF2
