  to construct sp2 carbon–nitrogen (C–N) bonds using palladium, copper or nickel catalysis1,2. However, the incorporation of alkyl substrates to form sp3 C–N bonds remains one of the major challenges in the field of cross-coupling chemistry. Here we demonstrate that the synergistic combination of copper catalysis and photoredox catalysis can provide a general platform from which to address this challenge

  在过去的三十年中，利用钯、铜或镍催化构建 sp2 碳氮 (C-N) 键的方法的开发取得了相当大的进展1,2。然而，结合烷基底物形成sp3 C-N键仍然是交叉偶联化学领域的主要挑战之一。在这里，我们证明铜催化和光氧化还原催化的协同组合可以提供一个通用平台来应对这一挑战。该交叉偶联系统使用天然丰富的烷基羧酸和市售的氮亲核试剂作为偶联伙伴。它适用于各种伯、仲和叔烷基羧酸（通过碘鎓活化），以及大量氮亲核试剂：氮杂环、酰胺、磺酰胺和苯胺可以进行 C-N 偶联，提供 N-在室温下和短时间内（五分钟到一小时），烷基产品的效率从良好到优异。我们证明，这种 C-N 偶联方案使用含有多个胺基的底物进行高区域选择性，并且还可以应用于复杂的药物分子，从而能够快速构建分子复杂性和生物活性药物的后期功能化。铜催化和光氧化还原催化的结合在快速、室温偶联方案中形成 sp3 C-N 键，具有高效率和区域选择性以及广泛的底物范围。

  作者：Farhad Panahi、Fereshteh Jamedi、Nasser Iranpoor

  DOI：10.1002/ejoc.201501349

  日期：2016.2

  A Nickel-catalyzed reductive process is described for the direct amidation of benzyl and aryl halides using carbodiimides as the amidating agent. Moreover, aryl and benzyl C–O electrophiles such as triflate, acetate, tosylate, trityl ether, and pivalate were converted into amides using this method. The in-situ-generated Ni0 acts as a catalyst for the reaction at room temperature for benzylic substrates

Furthermore, stoichiometric reactions of [(phen)Cu(phth)2] with tBuOOtBu and (Ph(Me)2CO)2 at 100 °C without cyclohexane afforded N-methylphthalimide (Me-phth) from β-Me scission of the alkoxy radicals to form a methyl radical.

  我们报道了一系列罕见的铜催化烷烃与简单酰胺、磺酰胺和酰亚胺（即苯甲酰胺、甲苯磺酰胺、氨基甲酸酯和邻苯二甲酰亚胺）的反应，形成相应的 N-烷基产物。这些反应导致仲 C-H 键官能化超过叔 C-H 键，甚至发生在伯 C-H 键上。 [(phen)Cu(phth)] (1-phth) 和 [(phen)Cu(phth)2] (1-phth2) 是反应中的潜在中间体，已被分离并充分表征。研究了 1-phth 和 1-phth2 与烷烃、烷基自由基和自由基探针的化学计量反应，以阐明酰胺化的机理。催化和化学计量反应需要铜和 tBuOOtBu 来生成 N-烷基产物。在没有 tBuOOtBu 的情况下，1-phth 和 1-phth2 在 100 °C 下均不会与过量环己烷反应。然而，1-phth 和 1-phth2 与 tBuOOtBu 的反应分别以大约 70:20:30 的比例提供 N-环己基邻苯二甲酰亚胺
