The copyrolysis (620 deg C) of phenol and ortho- and para-halogenophenols with perfluoroethylene in a flow-type system was investigated. 1,1,2,2,3,3-hexafluoroindane was mostly obtained from phenol, anisole, and o-bromophenol; o-chlorophenol gives the same compounds as the main product together with 1,1,2,2,3,3-hexafluoro-4-chloroindane; in the case of o-fluorophenol the main reaction products are 1,1,2,2,3,3-hexafluoroindane and 1,1,2,2,3,3,4- and 1,1,2,2,3,3,5-heptafluoroindanes.With perfluoroethylene para-halogenophenols form 1,1,2,2,3,3-hexafluoro-5-halogenoindanes.The paths to the formation of the polyfluoroindanes are discussed.When heated with nitric acid, 1,1,2,2,3,3-hexafluoroindane gives mainly 4-nitro-1,1,2,2,3,3-hexafluoroindane, from which the corresponding amino derivative is obtained by reduction.
