Perfluoropenta-1,2-diene can be obtained by vigorous dehydrohalogenation with alkali-metal hydroxides of 2H,2H-3-chloro-octafluoro-1-iodopentane, 2H-3-chloro-octafluoropent-1-ene, or 2H,2H-nonafluoro-1-iodopentane. The second precursor is prepared by mild basic dehydroiodination of the first, which is synthesised from 1,1-difluoroethylene and 1-chlorohexafluoro-1-iodopropane, obtained, together with
