Complexes (1+) react with 6,6-diarylfulvenes C5H4C(C6H4X-4)2 to yield products C5H4C(C6H4X-4)2L2>(1+) in which the fulvene is bound to the metal through the five-membered ring.Corresponding reactions with (1+) yield complexesC5H4C(C6H4X-4)22>(1+) containing two fulvene ligands.Atmospheric oxidation of these complexes results in the linking of the exocyclic carbon atoms in the two fulvene ligands by a peroxide bridge.If the initial attack by O2 is on the metal, the subsequent rearrangement may be viewed either as a transfer of singlet oxygen from metal to ligands or as a nucleophilic attack by peroxide on the (probably somewhat positively charged) exocyclic carbon atoms of the fulvene ligands.
