Fluorinated ferrocenyl sulfonates undergo anionic thia-Fries rearrangements, whereas fluorinated ferrocenylsulfones allow for ortho lithiation. A rare ferrocene anellated 6,7,8,9-tetrafluorobenzo[c,e]-[1,2]oxathiine 5,5-dioxide was obtained by ortho lithiation of ferrocenyl (2,3,4,5,6-pentafluorobenzene)sulfonate followed by an intramolecular nucleophilic substitution.

氟磺酰基二茂铁、（三氟甲基磺酰基）二茂铁和新的二茂铁磺酸盐：二茂铁的定向邻位锂化和新的阴离子硫杂-弗里斯重排

氟化二茂铁基磺酸盐经历阴离子硫杂-弗里斯重排，而氟化二茂铁基砜允许邻位锂化。通过二茂铁（2,3,4,5,6-五氟苯）的邻位锂化获得了一种稀有的二茂铁络合的6,7,8,9-四氟苯并[ c,e ]-[1,2]氧噻吩5,5-二氧化物磺酸盐，然后是分子内亲核取代。
