Pentafluorobenzene is an organofluoride compound with the molecular formula C
6HF
5.[1] The compound consists of a benzene ring substituted with five fluorine atoms.[2] The substance is a colorless liquid with a boiling point similar to that of benzene.[3][4] It is prepared by defluorination of highly fluorinated cyclohexanes over hot nickel or iron.[5] Another method involved dehydrofluorination of polyfluorinated cyclohexane using hot aqueous solution of KOH.[6]
