Reaction of o-bis [(trimethylsilyl) ethynyl)]-benzene with cyclopentadienyldicarbonylcobalt as catalyst and reagent is described, yielding biphenylene derivatives and cobalt complexes bearing novel organic ligands, re-spectively.Sir: In the last decade, cobalt-catalyzed intra-and intermolecular acetylene and olefin cooligomerizationshave been investigated intensively, 1, 2 yielding a number of natural products1 23 and species of theoretical interest. 4 3-Hexene-l, 5-diyne derivatives, however, have not played a role, hitherto, although interesting strained molecules might be synthesized.
