  A palladium-catalyzed difluoromethylation of a series of heteroaryl chlorides, bromides and iodides under mild conditions is described. A wide range of heteroaryl halides such as pyridyl, pyrimidyl, pyrazyl, funanyl, thienyl, pyazolyl, imidazolyl, thiazolyl, and oxazolyl halides were efficiently difluoromethylated, thus providing medicinal chemists an alternative choice for the preparation of drug

• Inherent vs Apparent Chemoselectivity in the Kumada–Corriu Cross-Coupling Reaction

  The Kumada–Corriu reaction is a powerful tool for C–C bond formation, but is seldom utilized due to perceived chemoselectivity issues. Herein, we demonstrate that high-yielding couplings can occur in the presence of many electrophilic and heterocyclic functional groups. Our strategy is mechanically based, matching oxidative addition rates with the rate of syringe pump addition of the Grignard reagent

  Kumada-Corriu反应是形成C-C键的有力工具，但由于存在化学选择性问题，因此很少使用。在本文中，我们证明了在许多亲电和杂环官能团的存在下可以发生高产率的偶联。我们的策略是基于机械的，使氧化添加速率与格氏试剂的注射泵添加速率相匹配。连续输注ESI-MS研究发现了该策略有效的机械原因。

  effective for a wide variety of aryl bromide coupling partners, is predicated upon a halogen atom abstraction/nickel radical-capture mechanism that is generically successful across an extensive range of carbonyl substrates. The construction and use of arylacetic acid products have further enabled two-step protocols for the delivery of valuable building blocks for medicinal chemistry, such as aryldifluoromethyl

  在这里，我们证明了金属氧还原催化的亲电子交联机理为多种活化烷基氯的α-芳基化反应提供了统一的方法，包括α-氯酮，α-氯酸酯，α-氯酰胺，α-氯羧酸和苄基氯。 。该策略对多种芳基溴化物偶联伙伴有效，基于卤素原子的提取/镍自由基捕获机制，该机制普遍适用于广泛的羰基底物。芳基丙烯酸产品的构建和使用进一步实现了两步协议，可用于交付药用化学的重要组成部分，例如芳基二氟甲基和二芳基甲烷图案。
