Tricarbonyl(fulvene)chromium complexes react with anionic nucleophiles to give functionally substituted cyclopentadienyl derivatives. The nucleophilic attack occurs at the exocyclic carbon atom of the fulvene ligand. Addition of PPh2− to (η6-6,6-dimethylfulvene)Cr(CO)3 (1) yields the novel anion [(η5-C5H4C(CH3)2PPh2)Cr-(CO)3]−, which can be isolated as a K+, (C2H5)4N+, (C6H5)4P+, or Tl+ derivative
