  Synthesis of Fulvalene-Bridged Bimetallic Compounds Containing a Substituted Cyclopentadienyl Group Based on Pauson−Khand Chemistry

  摘要：

  From the Pauson-Khand products 2-ferrocenylcyclopentenone (2) and 2-ferrocenyl-3-methylcyclopentenone (10) as starting materials, substituted ferrocene complexes (C5H5-eta(5)-C5H4)Fe(C5H5) (4), (CH3C5H4-eta(5)-C5H4)Fe(C5H5) (12), and (Me2C5H3-eta(5)-C5H4)Fe(C5H5) (16) were prepared. Metalation of 4, 12, and 16 with Mn(CO)(5)Br, Cr(CO)(3)(CH3CN)(3), FeCl2(THF)(n), and the deprotonated form of [CpFe(fluorene)](+) resulted in good yields of fulvalenyl-bridged heterobi- and polymetallic compounds. The molecular structures of [1-{(C5H4)Fe(C5H5)}-2-CH3C5H4]Mn(CO)(3) (13), [2-{(C5H4)Fe(C5H5)}-1,3-Me2C5H2] Mn(CO)(3) (17), [2-{(C5H4)Fe(C5H5)}-1,3-Me2C5H2]Fe(C5H5) (18), and [1-{(C5H4)Fe(C5H5)}-2,3,4,5-Me4C5]Fe(C5H5) (23) are reported.

• Synthesis of 1,2-Disubstituted Cyclopentadienes from Alkynes Using a Catalytic Haloallylation/Cross-Coupling/Metathesis Relay

  A three-step method based on Pd-catalyzed haloallylation of alkynes, Pd-catalyzed cross-coupling, and Ru-catalyzed ring-closing metathesis constitutes a new and short approach to variety of 1,2-substituted cyclopentadienes. The scope of the method is broad with respect to different substituents (alkyl, aryl, metallocenyl, and other substituents as well as their combinations are tolerated), and all

  基于Pd催化的炔烃卤代烯丙基化，Pd催化的交叉偶联和Ru催化的闭环复分解反应的三步法，构成了各种1,2取代的环戊二烯的新方法。关于不同的取代基（容许烷基，芳基，金属茂基和其他取代基以及它们的组合），该方法的范围很广，并且所有步骤均以合理的收率进行。作为产品用途的证明，将几种制备的环戊二烯转化为相应的二茂铁。
