A series of new halogenated aryl sulfonamides, as bio-active candidates, was synthesized from the reaction of the corresponding aryl sulfonamides with pentafluoro- and pentachloropyridines. Surprisingly, unlike aryl sulfonamides, the reaction of sulfamides with pentafluoro- and pentachloropyridines gave unexpected bis-perfluoro(chloro)pyridin-4-ylamines.

含全卤吡啶部分作为生物活性候选物的N取代磺酰胺的合成

通过相应的芳基磺酰胺与五氟和五氯吡啶的反应，合成了一系列新的卤化芳基磺酰胺作为生物活性候选物。令人惊讶地，与芳基磺酰胺不同，磺酰胺与五氟-和五氯吡啶的反应产生了出人意料的双全氟（氯）吡啶-4-基胺。
