    Nickel-Catalyzed Asymmetric α-Arylation and Heteroarylation of Ketones with Chloroarenes: Effect of Halide on Selectivity, Oxidation State, and Room-Temperature Reactions
    摘要:
    We report the alpha-arylation of ketones with a range of aryl chlorides with enantioselectivities from 90 to 99% ee catalyzed by the combination of Ni(COD)(2) and (R)-BINAP and the coupling of ketones with a range of heteroaryl chlorides with enantioselectivities up to 99% ee catalyzed by Ni(COD)(2) and (R)-DIFLUORPHOS. The analogous reactions of bromoarenes occur with much lower enantioselectivities. Mechanistic studies showed that the difference in the rates of decomposition of the arylnickel(II) halide intermediates to {[(R)-BINAP]NiX}(2) likely accounts for the difference in the enantioselectivities of the reactions of bromoarenes and chloroarenes. This catalyst decomposition can be overcome by conducting the reactions with [(R)-BINAP]Ni(eta(2)-NC-Ph) (4), which undergoes oxidative addition to haloarenes at room temperature.

    螯合膦与Ni(cod)2反应的综合研究
    摘要:
    介绍了螯合膦与Ni(cod)2形成(膦)Ni(cod),(膦)2 Ni或其混合物的反应的综合研究。分离并表征了一系列(膦)Ni(cod)配合物。使用X射线晶体学,1 H和31 P NMR光谱检查了(膦)Ni(cod)和(膦)2 Ni配合物之间的结构差异。另外,研究了环尺寸,刚性和膦骨架的体积对(膦)Ni(cod)或(膦)2 Ni的形成的影响。这些研究表明,(膦)Ni(cod)和(膦)2中的Ni-P键长度Ni络合物以及由螯合膦和Ni形成的环的大小对于确定是否可以分离(膦)Ni(cod)络合物至关重要。发现其他因素(例如π堆积相互作用)具有边际影响。

  • Identification of the Active Catalyst for Nickel‐Catalyzed Stereospecific Kumada Coupling Reactions of Ethers

    the stereospecific cross-coupling of benzylic ethers. These results demonstrate rapid redox reactions of precatalysts, such that the oxidative state of the precatalyst does not dictate the oxidation state of the active catalyst in solution. These data provide the first experimental evidence for a Ni0 -NiII catalytic cycle for a stereospecific alkyl-alkyl cross-coupling reaction, including spectroscopic

    The oxidative addition of 2,4,6-trichloroanisole (TCA) to Ni(0)(BINAP)(η2-PhCN) (2) represents a valuable procedure for the TCA detection in wine-stoppers due to the formation of the Ni (II) complex (4), showing a distinguishing UV-visible spectrum. Product 4 was characterized by X-ray analysis and allowed the indirect TCA determination in polluted corks as also demonstrated by the principal component

    extremely rare. Herein, we demonstrate that such stereodivergence can be achieved for nickel-catalyzed hydroboration of internal allenes, which enables convenient synthesis of both stereoisomers of trisubstituted alkenylboronates from the same starting reagents. Mechanistic studies reveal that these nickel-catalyzed allene hydroboration reactions do not follow conventional hydrometallation or borylmetallation
    开发多取代烯基硼酸酯的立体发散合成方案将简化和统一多取代烯烃的Z和E立体异构体的合成。尽管已经做出巨大努力来设计立体选择性方法来访问Z - 或E-alkenylboronates,在其合成中催化剂控制的立体发散仍然极为罕见。在此,我们证明了这种立体分歧可以通过催化的内部丙二烯氢化反应实现,这使得从相同的起始试剂中可以方便地合成三取代烯基硼酸酯的两种立体异构体。机理研究表明,这些催化的丙二烯氢化反应不遵循使用氢化物中间体的传统氢属化或属化途径。在潜在中间体的合成及其化学计量反应的基础上,我们提出了这种催化的丙二烯氢化反应的新途径,Z - 或E -烯基硼酸盐。

    日期:2002.9.1
    The efficient preparation of [(S)-BINAP]Ni-(COD) (1) and [(S)-BINAP]NiBr2 (2) is reported. X-ray crystal structure analysis of these potential precatalysts provides the first structural insights into the nickel-BINAP system at both the 0 and +2 oxidation states.
