Bromopentafluorobenzene is an
organofluorine compound with the formula C
6F
5Br. It is a colorless liquid that is used to prepare pentafluophenyl compounds. These syntheses typically proceed via the intermediacy of C
6F
5Li or the
Grignard reagent
A Grignard reagent or Grignard compound is a chemical compound with the general formula , where X is a halogen and R is an organic group, normally an alkyl or aryl. Two typical examples are methylmagnesium chloride and phenylmagnesium bromide ...
