  • A Mild and Ligand-Free Ni-Catalyzed Silylation via C–OMe Cleavage

    日期:2017.1.25
    of central importance in organic synthesis. Despite the formidable potential of aryl methyl ethers as coupling partners, the scarcity of metal-catalyzed C-heteroatom bond formations via C-OMe cleavage is striking, with isolated precedents requiring specialized, yet expensive, ligands, high temperatures, and π-extended backbones. We report an unprecedented catalytic ipso-silylation of aryl methyl ethers
    形成碳-杂原子键的属催化转化在有机合成中至关重要。尽管芳基甲基醚作为偶联伙伴具有巨大的潜力,但通过 C-OMe 裂解形成的属催化 C-杂原子键的稀缺性令人震惊,孤立的先例需要专门但昂贵的配体、高温和 π 扩展主链. 我们报告了在温和条件下且无需借助外部配体的芳基甲基醚的前所未有的催化 ipso-甲硅烷基化。该方法以其广泛的范围而著称,其中包括使用苄基甲基醚乙烯基甲基醚和无偏苯甲醚生物,因此代表了通过 C-OMe 断裂设计新的 C-杂原子键形成的重要一步。还描述了这种转化在正交甲硅烷基化技术以及进一步衍生化中的应用。初步的机械实验表明 Ni(0)-ate 复合物的中介作用,这使得由 C-OMe 键初始氧化加成到 Ni(0) 物种组成的典型催化循环开始发挥作用存在一些疑问。

    An efficient Fe(TPP)Cl catalyzed insertion reaction of in situ generated benzylic carbenes from N-tosylhydrazones into X–H (X = Si, Sn, Ge) was developed. Silanes bearing tertiary, secondary, and primary (3°, 2°, and 1°) Si–H bonds all reacted well to afford insertion products in moderate to high yields (up to 97%), and the reaction time could be significantly shortened to 1 h under microwave irradiation

    Pd(0)-Catalyzed formal carbene insertion into Si–H bonds has been achieved as an efficient method for C(sp3)–Si bond formation. The reaction, which uses readily available N-tosylhydrazones as the diazo precursors, is highly efficient and shows a wide substrate scope.

The resulting benzyl silane moiety can undergo the post functionalizations to deliver the more complex diarylmethane derivatives. Additionally, the related base-free allylic silylation reaction is also demonstrated.

  • Organopotassium‐Catalyzed Silylation of Benzylic C(<i>sp</i><sup>3</sup>)−H Bonds

    Abstract

    Benzylsilanes have found increasing applications in organic synthesis as bench‐stable synthetic intermediates, yet are mostly produced by stoichiometric procedures. Catalytic alternatives based on the atom‐economical silylation of benzylic C(sp3)−H bonds remain scarcely available as specialized directing groups and catalytic systems are needed to outcompete the kinetically‐favored silylation of C(sp2)−H bonds. Herein, we describe the first general and catalytic‐in‐metal undirected silylation of benzylic C(sp3)−H bonds under ambient, transition metal‐free conditions using stable tert‐butyl‐substituted silyldiazenes (tBu−N=N−SiR3) as silicon source. The high activity and selectivity of the catalytic system, exemplified by the preparation of various mono‐ or gem‐bis benzyl(di)silanes, originates from the facile generation of organopotassium reagents, including tert‐butylpotassium.

    摘要苄基硅烷作为稳定的合成中间体,在有机合成中的应用日益广泛,但大多是通过化学计量法生产的。基于苄基 C(sp3)-H 键原子经济硅烷化的催化替代品仍然很少,因为需要专门的定向基团和催化系统才能与动力学上有利的 C(sp2)-H 键硅烷化竞争。在本文中,我们首次介绍了以稳定的叔丁基取代的二氮(tBu-N=N-SiR3)为源,在无过渡属的环境条件下,对苄基 C(sp3)-H 键进行的通用属内催化非定向硅烷化反应。该催化系统的高活性和高选择性源于有机钾试剂(包括叔丁基)的简便生成,以制备各种单苄基或双苄基(二)硅烷为例。
