Pentafluorobenzene Explained

Pentafluorobenzene is an organofluoride compound with the molecular formula .^[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]
