  • Highly Selective and Divergent Acyl and Aryl Cross-Couplings of Amides via Ir-Catalyzed C–H Borylation/N–C(O) Activation
    作者:Pengcheng Gao、Michal Szostak
    DOI:10.1021/acs.orglett.0c02105
    日期:2020.8.7
    Herein, we demonstrate that amides can be readily coupled with nonactivated arenes via sequential Ir-catalyzed C–H borylation/N–C(O) activation. This methodology provides facile access to biaryl ketones and biaryls by the sterically controlled Ir-catalyzed C–H borylation and divergent acyl and decarbonylative amide N–C(O) and C–C activation. The methodology diverts the traditional acylation and arylation
    在这里,我们证明酰胺可以通过连续的Ir催化的C–H硼酸酯化/ N–C(O)活化而容易地与未活化的芳烃偶联。这种方法可通过空间控制的Ir催化的C–H硼化以及不同的酰基和脱羰基酰胺N–C(O)和C–C活化来轻松获得联芳基酮和联芳基。该方法转移了传统的酰化和芳基化区域选择性,使我们能够直接利用容易获得的芳烃和酰胺来产生有价值的酮和联芳基。
  • Hydrogenation of (Hetero)aryl Boronate Esters with a Cyclic (Alkyl)(amino)carbene–Rhodium Complex: Direct Access to <i>cis</i> ‐Substituted Borylated Cycloalkanes and Saturated Heterocycles
    作者:Liang Ling、Yuan He、Xue Zhang、Meiming Luo、Xiaoming Zeng
    DOI:10.1002/anie.201811210
    日期:2019.5.13
    We herein report the hydrogenation of substituted aryl‐ and heteroaryl boronate esters for the selective synthesis of cis‐substituted borylated cycloalkanes and saturated heterocycles. A cyclic (alkyl)(amino)carbene‐ligated rhodium complex with two dimethyl groups at the ortho‐alkyl scaffold of the carbene showed high reactivity in promoting the hydrogenation, thereby enabling the hydrogenation of
    我们在此报告了取代的芳基和杂芳基硼酸酯的氢化反应,用于选择性合成顺式取代的硼化环烷烃和饱和杂环。在卡宾的邻烷基支架上带有两个二甲基的环状(烷基)(氨基)卡宾连接的铑配合物在促进氢化方面显示出高反应活性,从而使(杂)芳烃得以氢化并保留了合成有价值的硼酸酯团体。该过程构成了清洁,原子经济以及化学和立体选择性的途径,用于生成通常难以捉摸且难以制备的顺式构型,不同取代的硼酸化环烷烃和饱和杂环。
  • Oxygen-Promoted Pd(II) Catalysis for the Coupling of Organoboron Compounds and Olefins
    作者:Young Chun Jung、Rajesh Kumar Mishra、Cheol Hwan Yoon、Kyung Woon Jung
    DOI:10.1021/ol034458s
    日期:2003.6.1
    Reported herein is a mild and efficient Pd(II) catalysis, leading to the formation of carbon-carbon bonds between a broad spectrum of organoboron compounds and alkenes. Molecular oxygen was employed to reoxidize the resultant Pd(0) species back to Pd(II) during catalytic cycles. This oxygen protocol promoted the desired Pd(II) catalysis, whereas it retarded competing Pd(0) catalytic pathways such as
    本文报道的是温和有效的Pd(II)催化作用,导致在宽范围的有机硼化合物和烯烃之间形成碳-碳键。在催化循环过程中,使用分子氧将生成的Pd(0)物种重新氧化回Pd(II)。该氧方案促进了所需的Pd(II)催化作用,而它却阻碍了竞争的Pd(0)催化途径,例如Heck或Suzuki偶联。[反应:看文字]
  • Transition-Metal-Free <i>ipso</i>-Trifluoromethylthiolation of Lithium Aryl Boronates
    作者:Feng Shen、Hanliang Zheng、Xiao-Song Xue、Long Lu、Qilong Shen
    DOI:10.1021/acs.orglett.9b02236
    日期:2019.8.16
    A transition-metal-free direct trifluoromethylthiolation of the ipso-carbon of lithium aryl boronates with trifluoromethanesulfenate under mild conditions was described. In addition, late-stage site-selective C–H borylation/trifluoromethylation and C–Cl borylation/trifluoromethylthiolation of biologically active molecules was developed. Initial mechanistic study suggested that the Li+ cation plays
    的过渡金属-自由直接trifluoromethylthiolation本位被描述用温和的条件下trifluoromethanesulfenate锂芳基硼酸酯的碳上。此外,还开发了生物活性分子的后期现场选择性C–H硼化/三氟甲基化和C–C1硼化/三氟甲基硫醇化。最初的机理研究表明,Li +阳离子通过与芳基硼酸酯络合物的氧原子和试剂的氧配位发挥至关重要的作用,从而使芳基直接攻击三氟甲基硫醇化试剂的三氟甲硫基。
  • Two Ligands Transfer from Ag to Pd: En Route to (SIPr)Pd(CF<sub>2</sub>H)(X) and Its Application in One-Pot C–H Borylation/Difluoromethylation
    作者:Haiwei Zhao、Simon Herbert、Tom Kinzel、Wei Zhang、Qilong Shen
    DOI:10.1021/acs.joc.9b03296
    日期:2020.3.6
    A process for the concurrent transfer of both the NHC ligand and the difluoromethyl group from [(SIPr)Ag(CF2H)] to PdX2 (X = Cl, OAc, and OPiv) for the preparation of [(SIPr)Pd(CF2H)X] complexes is described. These complexes were air-stable and easily underwent transmetalation with aryl pinacol boronate/reductive elimination to generate ArCF2H in high yields. Based on this discovery, the first one-pot
    NHC配体和二氟甲基基团从[(SIPr)Ag(CF2H)]同时转移到PdX2(X = Cl,OAc和OPiv)的过程,用于制备[(SIPr)Pd(CF2H)X描述复合物。这些络合物是空气稳定的,易于通过芳基频哪醇硼酸酯/还原消除进行重金属化,从而以高收率生成ArCF2H。基于这一发现,开发了用于制备二氟甲基化(杂)芳烃的第一个单锅CH硼化和二氟甲基化方法。
