We report herein the transfer of dual photoredox and nickel catalysis for C(sp2)C(sp3) cross coupling form batch to flow. This new procedure clearly improves the scalability of the previous batch reaction by the reactor’s size and operating time reduction, and allows the preparation of interesting compounds for drug discovery in multigram amounts.

carbon centers adjacent to nitrogen or oxygen. The use of sp3 C–Hbonds—which are ubiquitous in organic molecules—as latent nucleophile equivalents for transition metal–catalyzed cross-coupling reactions has the potential to substantially streamline synthetic efforts in organic chemistry while bypassing substrate activation steps. Through the combination of photoredox-mediated hydrogen atom transfer (HAT)
从 HAT 到 CC 键的形成 铱和镍已经是锻造碳-碳键的成熟团队。铱从一个简单的发光二极管收集蓝光,并通过镍协调耦合。肖等人。现在为团队添加第三名球员,即氢原子转移 (HAT) 催化剂(参见 Fruit 的观点)。这三种催化剂一起可以将溴或氯芳基环直接连接到与氮或氧相邻的 CH 位点,无需事先修饰。该反应对广泛的底物具有高度选择性。科学,这个问题 p。1304; 另见第。1277 三种催化剂将芳环附加到与氮或氧相邻的各种碳中心。使用 sp3 C-H 键(在有机分子中普遍存在)作为过渡金属催化交叉偶联反应的潜在亲核试剂等价物,有可能大大简化有机化学中的合成工作,同时绕过底物活化步骤。通过光氧化还原介导的氢原子转移 (HAT) 和镍催化的结合,我们开发了一种高选择性和通用的 C-H 芳基化方案,可激活各种 C-H 键作为交叉偶联的天然功能手柄。这种温和的方法利用可调节的 HAT 催化剂,该催
