  Transition metal catalysis that utilizes N-heterocyclic carbenes as noninnocent ligands in promoting transformations has not been well studied. We report here a cyclic (alkyl)(amino)carbene (CAAC) ligand-promoted nitro deoxygenative hydroboration with cost-effective chromium catalysis. Using 1 mol % of CAAC-Cr precatalyst, the addition of HBpin to nitro scaffolds leads to deoxygenation, allowing for

  利用 N-杂环卡宾作为非无害配体促进转化的过渡金属催化尚未得到很好的研究。我们在这里报告了具有成本效益的铬催化的环状（烷基）（氨基）卡宾（CAAC）配体促进的硝基脱氧硼氢化反应。使用 1 mol % 的 CAAC-Cr 预催化剂，将 HBpin 添加到硝基支架上会导致脱氧，从而保留各种可还原的官能团和敏感基团对硼氢化的相容性，从而提供一种温和、化学选择性和易于形成的策略苯胺，以及杂芳基和脂肪胺衍生物，具有广泛的范围和特别高的转换数（高达 1.8 × 106）。基于理论计算的机械研究，表明CAAC配体在促进HBpin氢化物极性反转中起重要作用；它用作 H 穿梭以促进脱氧硼氢化。通过这种策略制备的几种市售药物突出了其在药物化学中的潜在应用。

  The Chan–Evans–Lam reaction is a valuable C–N bond forming process. However, aryl boronic acid pinacol (BPin) ester reagents can be difficult coupling partners that often deliver low yields, in particular in reactions with aryl amines. Herein, we report effective reaction conditions for the Chan–Evans–Lam amination of aryl BPin with alkyl and aryl amines. A mixed MeCN/EtOH solvent system was found

  Chan–Evans–Lam反应是有价值的C–N键形成过程。但是，芳基硼酸频哪醇（BPin）酯试剂可能很难成为偶合剂，常常导致收率低，特别是在与芳基胺反应时。在此，我们报告了烷基-芳基胺与芳基BPin的Chan-Evans-Lam胺化反应的有效反应条件。发现混合的MeCN / EtOH溶剂系统可以使用芳基胺形成有效的C–N键，而烷基胺的偶联则不需要EtOH。
