Ferrocenesulfonyl chloride is the keyintermediate in the synthesis of ferrocenesulfonamides, a family of underexplored derivatives. A one-pot synthesis of this compound, able to easily deliver multigram quantities of product, is reported. An original protocol for the synthesis of ferrocenesulfonamides is described along with highlighting the reactivity difference between arene and ferrocenesulfonyl

Deuteriumexchange of certain substituted ferrocenes (under very mild basic conditions) occurs in only the substituted cyclopentadienyl-ring in nonstatistical pattern; a π→σ(η5→η1) rearrangement mechanism is proposed to account for the novel pattern of exchange.
