| Abstract: |
A new ferrocenylphenyl butadiynyl compound Fc–C6H4–(C≡C)2–C6H5 (L) has been synthesized by the Glaser cross-coupling reaction and three new complexes with a 4-ferrocenylphenyl-μ-alkyne-dicobalt moiety, [Fc–C6H4–(C≡C)n–R][Co2(CO)6]n′ [Fc=C5H5FeC5H4, R=H, n=1, n′=1 (1); R=C6H5, n=2, n′=2 (2); R=Fc-C6H4, n=2, n′=2 (3) ], were obtained in the reaction of p-ferrocenylphenylacetylene compounds with Co2(CO)8. Compounds L, 1, 2 and 3 were characterized by elemental analysis, IR, 1H, 13C NMR and MS. The molecular and crystal structures of compounds L and 2 have been determined by X-ray single crystal analysis. There is a linear C5H4–C6H4–(C≡C)2–C6H5 linkage in compound L, and the terminal ferrocenylphenyl and phenyl groups in complex 2 are a cis arrangement. [Copyright &y& Elsevier] |
