  摘要：

  (eta(6)-Arene)Co(I)) complexes stabilized by bisphosphines, e.g. [(eta(6)-MeC6H5)Co((Pr2PC2H4PPr2i)-P-i)] (+) BF4- have been prepared by reacting (eta(3)-cyclooctenyl)Co(bisphosphine) species with HBF4 in the presence of an arene. The (eta(6)-C6H6)Co(I) compounds can also be prepared by hydrogen abstraction from the corresponding (eta(5)-cyclohexadienyl)Co(I) complex or by hydrogenation of (eta(3)-cyclooctenyl)Co(II) species in the presence of benzene. Facile arene-exchange occurs upon treatment of these compounds with a second arene. In contrast. (eta(3)-cyclohexenyl)Co(I) and (eta(5)-cycloheptadienyl)CoO complexes are oxidized by HBF4 in the presence of an alkene to give (eta(3)-cyclohexenyl)Co(II) and (eta(5)-cycloheptadienyl)Co(II) species: the former have been characterized as their diamagnetic NO adducts and the latter by a crystal structure determination.
