  • Ligand-Induced Regioselectivity in Metal-Catalyzed Aryne Reactions Using Borylaryl Triflates as Aryne Precursors
    作者:Brylon N. Denman、Erin E. Plasek、Courtney C. Roberts
    DOI:10.1021/acs.organomet.3c00103
    日期:2023.5.22
    The utility of reactions using unsymmetrically substituted aryne intermediates can be negatively impacted by issues with regioselectivity as these reactions are substrate controlled. This leaves no avenues for improving regioselectivity without altering the substrate which has led to numerous reports about how to enhance or reverse this regioselectivity in metal-free aryne reactions by changing the
    使用不对称取代的芳烃中间体的反应效用可能会受到区域选择性问题的负面影响,因为这些反应是底物控制的。这就没有途径可以在不改变底物的情况下提高区域选择性,这导致了大量关于如何通过改变电子元件来增强或逆转无芳烃反应中的区域选择性的报道。对于具有属结合芳烃中间体的系统,不存在此类研究,这些系统通常具有较差的区域选择性。在此,我们报道了一种通过催化剂控制在属催化的芳烃二官能团化中实现区域选择性的方法。通过使用不对称的配体环境,可以诱导选择性(高达 9:91 r.r.)。这些研究表明,催化剂设计会影响属催化芳烃反应的选择性。
  • Generation of Arynes via Ate Complexes of Arylboronic Esters with an <i>ortho</i>-Leaving Group
    作者:Yuto Sumida、Tomoe Kato、Takamitsu Hosoya
    DOI:10.1021/ol401140d
    日期:2013.6.7
    An efficient method of generating aryne has been achieved by treating ortho-(trifluoromethanesulfonyloxy)arylboronic acid pinacol ester with tert-or sec-butyllithium. Monitoring the reaction by B-11 NMR has indicated that a boron-ate complex formed in situ is the eventual precursor that converts into aryne near room temperature. The prior formation of the ate complex at a low temperature has enabled us to use various arynophiles, including those bearing base-sensitive groups. The ready availability of the aryne precursors and mutual orthogonality in aryne generation with widely used ortho-silylaryl triflate have enhanced the utility of the method.
  • Ir-Catalyzed ortho-Borylation of Phenols Directed by Substrate–Ligand Electrostatic Interactions: A Combined Experimental/in Silico Strategy for Optimizing Weak Interactions
    作者:Buddhadeb Chattopadhyay、Jonathan E. Dannatt、Ivonne L. Andujar-De Sanctis、Kristin A. Gore、Robert E. Maleczka、Daniel A. Singleton、Milton R. Smith
    DOI:10.1021/jacs.7b02232
    日期:2017.6.14
    A strategy for affecting ortho-versus meta/para selectivity in Ir-catalyzed C-H borylations (CHBs) of phenols is described. From selectivity observations with ArylOBpin (pin-7 pinacolate), it is hypothesized that an electrostatic interaction between the partial negatively,charged OBpin group and the partial positively charged bipyridine ligand of the catalyst favors ortho selectivity. Experimental and computational studies designed to test this hypothesis support it. From further computational work a second generation, in silico designed catalyst emerged; where replacing Bpin with Beg (eg, = ethylene glycolate) was predicted to significantly improve ortho selectivity. Experinientally, reactions employing B(2)eg(2) gave ortho selectivities > 99%. Adding triethylamine significantly improved conversions. This ligand-substrate electrostatic interaction provides a unique control element for selective C-H functionalization.
