Photochemical chlorination of pentafluoropyridine yields 2,3,4,5-tetrachloro-2,3,4,5,6-pentafluorotetrahydropyridine, hydrolysis of which affords 2,3,4-trichloro-2,3,4-trifluoropentanedioic acid. Bistrifluoromethyl nitroxide reacts with pentafluoropyridine to yield perfluoro-2,3,4,5-tetrakis(dimethylamino-oxy)tetrahydropyridine, and with perfluorocyclohexene to give perfluoro-[1,2-bis(dimethylamino-oxy)cyclohexane]
五氟吡啶的光化学氯化得到2,3,4,5-四氯-2,3,4,5,6-五氟四氢吡啶,其水解得到2,3,4-三氯-2,3,4-三氟戊二酸。双三氟甲基硝基氧与五氟吡啶反应生成全氟-2,3,4,5-四(二甲基氨基-氧基)四氢吡啶,并与全氟环己烯生成全氟-[1,2-双(二甲基氨基-氧基)环己烷]。全氟2,3,4,5-四氢吡啶可抵抗氯和双三氟甲基硝基氧的攻击。
