摘要: A simple method, utilizing a coupling reaction between ethynylferrocene and cis-1,2-dichloroethylene catalysed by Pd(PPh3)4/CuI or Pd(PPh3)2Cl2/CuI, for the stepwise preparation of ferrocenylbutadiyne is described. Complete 1H 13C NMR characterization (η-C5H5)Fe(η-C5H4)(CC)nH (n = 1, 2), (η-C5H5)Fe(η-C5H4)(CC)n(η-C5H4)Fe(η-C5H5) 2, 4) Z-(η-C5H5) Fe(η-C5H4)CCCHCHCl, an X-ray crystal structure study 1,4-bis(ferrocenyl)butadiyne, third order nonlinear optical behavior (second molecular hyperpolarizability, γ) 1,8-bis(ferrocenyl) octatetrayne are reported.
