Abstract
6,6-Diarylpentafulvenes upon coordination by odd-electron (trimethylph osphine)cobalt(0) moieties undergo a reductive C,C coupling reaction i n the 1-position of the C-5 ring, forming dinuclear (eta(3)-allyl)coba lt(I) compounds. The C,C coupling is reversed under ambient conditions by reaction of the metal with carbon monoxide. Even-electron methyl- or phenyl(trimethylphosphine)cobalt(I) moieties accommodate 6,6-diaryl fulvenes as eta(4)-diene ligands in mononuclear complexes.
