Bromopentafluorobenzene is an organofluorine compound with the formula C6F5Br.

It is a colorless liquid that is used to prepare pentafluophenyl compounds.

These syntheses typically proceed via the intermediacy of C6F5Li or the Grignard reagent.

[1] Illustrative is preparation of tris(pentafluorophenyl)borane:[2] Other derivatives include LiB(C6F5)4,[3] [CuC6F5]4,[1] and Ni(C6F5)2(dioxane)2.
