Investigation of the Reaction of Allyl(cyclopentadienyl)iron(II) Dicarbonyl with Iminium Salts: Synthesis of Ammonium Salts of Substituted Five-Membered-Ring Iron Complexes

Series of quaternary ammonium salts of substituted five-membered-ring iron complexes were prepared by reaction of allyl(cyclopentadienyl)iron(II) dicarbonyl with iminium salts. Also, reactions of allyl-(cyclopentadienyl)iron(II) dicarbonyl with in situ prepared iminium salts afford the same products in good to excellent isolated yields.
