    Arylalkene Synthesis via Decarboxylative Cross-Coupling of Alkenyl Halides
    摘要:
    A bimetallic catalyst system generated from readily available palladium(II) and copper(I) salts, 1,10-phenanthroline and tri-1-naphthylphosphine was found to efficiently mediate the decarboxylative cross-coupling of alkenyl bromides and chlorides with aromatic carboxylates. It allows the regiospecific synthesis of a broad range of aryl- and heteroarylalkenes in high yields.

    practical using an electroreductive manifold. Although early studies pointed to the feasibility of such a process, those precedents were never applied by others due to cumbersome setups and limited scope. Here we show that a carefully optimized electroreductive procedure can enable a more sustainable approach to NHK, even in an asymmetric fashion on highly complex medicinally relevant systems. The e-NHK
    最常用的 C-C 键形成方法之一是使用还原歧管,使卤乙烯与 Ni 和 Cr 催化的醛偶联(Nozaki-Hiyama-Kishi,NHK)变得更加实用。尽管早期研究指出了这种过程的可行性,但由于设置繁琐且范围有限,这些先例从未被其他人应用。在这里,我们展示了经过精心优化的电还原程序可以使 NHK 采用更可持续的方法,即使在高度复杂的医学相关系统上以不对称方式也是如此。当传统化学技术失败时,e-NHK 甚至可以使非规范底物类别(例如氧化还原活性酯)参与低负载量的 Cr。详细的动力学、循环伏安法、

    A facile Pd-catalyzed conversion of aryl and vinyl triflates to aryl and vinyl halides (bromides and chlorides) is described. This method allows convenient access to a variety of aryl, heteroaryl, and vinyl halides in good to excellent yields and with greatly simplified conditions relative to our previous report.

    In the presence of a ruthenium catalyst, alkenyl triflates were found to be transformed to the corresponding bromides, chlorides and iodides simply by treatment with a lithium halide (1.2 equiv.).

    coupling reactions has increased over the past decade. Surprisingly, the use and synthesis of alkenyl fluorosulfonates is still poorly described. In this paper, the advantageous use of aryl and alkenyl fluorosulfonates instead of the corresponding triflates is reported to synthesize aryl and alkenyl halides using halide salts and commercially available ruthenium catalysts.

  • Ruthenium-Catalyzed Transformation of Aryl and Alkenyl Triflates to Halides
    作者:Yusuke Imazaki、Eiji Shirakawa、Ryota Ueno、Tamio Hayashi
    DOI:10.1021/ja307771d
    日期:2012.9.12
    Aryl triflates were transformed to aryl bromides/iodides simply by treating them with LiBr/NaI and [Cp*Ru(MeCN)(3)]OTf. The ruthenium complex also catalyzed the transformation of alkenyl sulfonates and phosphates to alkenyl halides under mild conditions. Aryl and alkenyl triflates undergo oxidative addition to a ruthenium(II) complex to form eta(1)-arylruthenium and 1-ruthenacyclopropene intermediates, respectively, which are transformed to the corresponding halides.
