  • Cobalt-Mediated Two-Carbon Ring Expansion of Five-Membered Rings. Electrophilic Carbon−Carbon Bond Activation in the Synthesis of Seven-Membered Rings
    作者:Trevor L. Dzwiniel、Jeffrey M. Stryker

    Electrophilic cobalt(III) mediates an unprecedented two-carbon ring expansion of coordinated five-membered rings, leading to a remarkably general new strategy for the synthesis of seven-membered carbocycles from readily available five-membered ring substrates. The reaction, a metal-mediated [5 + 2] cyclopentenyl/alkyne cycloaddition, proceeds via initial protonation of a cobalt(I) cyclopentadiene complex
    亲电性钴 (III) 介导了前所未有的配位五元环的双碳环扩展,从而为从现成的五元环底物合成七元碳环提供了一种非常普遍的新策略。该反应是金属介导的 [5 + 2] 环戊烯基/炔环加成,通过钴 (I) 环戊二烯配合物的初始质子化进行,然后重排为 eta3-环戊烯基中间体。环状 eta3-烯丙基残基随后与炔烃发生迁移偶联,随后无应变的五元环的碳-碳键活化并再循环为扩环产物,尽管事件的顺序和密切机制尚未最终确定。该反应对于五元环配体的活化具有高度选择性,这可能是快速钴介导的环间氢化物转移和炔插入较少取代的环戊烯基环的动力学偏好的结果。炔烃插入本身是高度区域选择性的,通过迁移到炔烃的空间较小的末端进行。该反应对钴抗衡离子和辅助的 eta5-环戊二烯基取代基都很敏感,但对相当范围的烷基-、芳基-和三烷基甲硅烷基取代的末端和内部炔烃进行。炔烃插入本身是高度区域选择性的,通过迁移到炔烃的空间较小的末端进行。该反应对钴抗衡离子和辅助的

  • Synthesis and Physical Properties of Pentamethylmanganocene, (C<sub>5</sub>Me<sub>5</sub>)Mn(C<sub>5</sub>H<sub>5</sub>), and the Inclusion Compounds [(C<sub>5</sub>Me<sub>5</sub>)<sub>2</sub>Yb]<sub>2</sub>[(C<sub>5</sub>H<sub>5</sub>)<sub>2</sub>M] (Where M = V, Cr, Fe, Co)

    The inclusion complexes of composition (Cp*Yb-2)(2)(Cp2M) (M = V, Cr, Fe, and Co; Cp* = eta(5)-C5Me5; Cp = eta(5)-C5H5) are isolated in the solid state. The crystal structure of one of them, M = Co, shows that the Cp2Co metallocene is sandwiched between two Cp*Yb-2 metallocenes with two long Yb center dot center dot center dot C bond distances of 2.914(6) angstrom, one from each of the Cp rings of Cp2Co. When M = Mn and Ni are used, the ring exchange products, Cp*MCp, are isolated along with Cp*YbCp, a hydrocarbon-insoluble green solid isolated as the thf adduct. This Cp for Cp* exchange reaction is the only currently available synthesis for the low-spin pentamethylmanganocene and the pentamethylytterbocene. The crystal structures and magnetic and related physical properties of Cp*MCp, M = Mn, Co, and Ni (Organometallics 1985, 4, 1680), are reported and analyzed. The origin of the different relative rates of Cp* for Cp ring exchange is traced to the kinetic lability resulting from the (e(1g)*)(2) electronic structure of Cp2M, M = Mn and Ni.
