• Photoredox/Cobalt Dual Catalysis for Visible-Light-Mediated Alkene–Alkyne Coupling
  作者：Pramod Rai、Kakoli Maji、Biplab Maji

  日期：2019.5.17

  Dual photoredox transition-metal catalysis has recently emerged as a powerful tool for making synthetically challenging carbon–carbon bonds under milder reaction conditions. Herein, we report on the visible-light-mediated controlled generation of low-valent cobalt catalyst without the need for a metallic reductant. It enabled C–C bond formation via ene-yne coupling at room temperature. The generality

  最近，双重光氧化还原过渡金属催化已成为一种在较温和的反应条件下制备具有挑战性的碳-碳键的有力工具。在本文中，我们报道了在不需要金属还原剂的情况下可见光介导的低价钴催化剂的受控生成。它可以在室温下通过ene-yne偶联形成C–C键。这种双重催化的普遍性通过容纳多个官能团的可观分子多样性的创造得到证明。

  unactivated C(sp3)–H and the reaction selectivity are among the core pursuits for transition-metal catalytic system development. Herein, we report Pd-catalyzed γ-C(sp3)–H-selective alkylation and alkenylation with removable 7-azaindole as a directing group. Acid and base were found to be the decisive regulators for the selective alkylation and alkenylation, respectively, on the same single substrate under otherwise

  远程未活化C（sp 3）–H的功能化和反应选择性是过渡金属催化系统开发的核心追求。在本文中，我们报道了Pd催化的γ-C（sp 3）–H-选择性烷基化和烯基化反应，其中可移动的7-氮杂吲哚为指导基团。发现在相同的单一底物上，否则在相同的反应条件下，酸和碱分别是选择性烷基化和烯基化的决定性调节剂。各种丙烯酸酯都适合形成C（sp 3）–C（sp 3）和C（sp 3）–C（sp 2）债券。烯基化方案可以进一步扩展至具有天然产物单元和α，β-不饱和酮的丙烯酸酯。烷基化和烯基化产物的初步合成操作证明了该策略在结构上多样化的脂族链延伸和官能化方面的潜力。机理实验研究表明，酸性和碱性催化转化共有相同的六元二聚体palladacycle。

  Alkyl chlorides are common functional groups in synthetic organic chemistry. However, the engagement of unactivated alkyl chlorides, especially tertiary alkyl chlorides, in transition-metal-catalyzed C-C bond formation remains challenging. Herein, we describe the development of a TiIII-catalyzed radical addition of 2° and 3° alkyl chlorides to electron-deficient alkenes. Mechanistic data are consistent

  烷基氯是合成有机化学中常见的官能团。然而，未活化的烷基氯，特别是叔烷基氯在过渡金属催化的 CC 键形成中的参与仍然具有挑战性。在此，我们描述了 TiIII 催化的 2° 和 3° 烷基氯与缺电子烯烃的自由基加成的发展。机理数据与以 TiIII 介导的 Cl 原子抽象为特征的 C-Cl 键的内球激活一致。有证据表明，活性 TiIII 催化剂是在路易斯酸辅助电子转移过程中由 TiIV 前体产生的。

  A straightforward strategy was developed for the arylation and olefination at the C5-position of the N-(alkyl)pyrimidin-2-amine core with readily available aryl halides and alkenes, respectively. This approach was highly regioselective, and the transformation was achieved based on two different (Pd(ii)/Pd(iv)) and (Pd(0)/Pd(ii)) catalytic cycles.
