  将光催化整体水分解与有机分子加氢耦合：使用水作为氢源和电子供体以实现加氢的策略

  摘要：

  在绿色化学中使用水作为氢源来实现有机分子的氢化是很有趣的。然而，由于整体水分解的高度困难，当前的光驱动策略受到用于质子还原的还原剂的费用的影响。在此，我们克服了这一挑战并报告了光诱导的整体水分解与芳基溴化物的氢化通过可回收的 Pd/gC 3 N 4之间的协同催化作用相结合。和 Fe 物种，这开辟了一条光催化途径，可以将水用作电子供体和氢源，以实现芳基溴化物的氢化，避免使用额外的还原剂。此外，温和的条件、可回收的催化剂系统和使用可见光作为能源使这一过程更加环保。本方法还可以有效合成各种高附加值的氘代芳烃。这项工作将指导化学家使用水作为电子供体和氢源来开发各种有机化合物加氢的绿色程序。

  practical synthesis of aryl and heteroaryl N‐acylureas has been developed via palladium‐catalysed carbonylation of aryl or heteroaryl halides in the presence of urea nucleophiles. A range of reactions illustrating the wide scope of this reaction was carried out under microwave irradiation, using either carbon monoxide gas in a vessel equipped with a gas inlet adapter, or molybdenum hexacarbonyl as the

  日期：2021.4

  transfer hydrogenation and borrowing hydrogen reactions paved the way to manipulate simple alcohols in previously unthinkable manners and circumvented the need for hydrogen gas. Analogously, transfer hydrocarbylation could greatly increase the versatility of tertiary alcohols. However, this reaction remains unexplored because of the challenges associated with the catalytic cleavage of unactivated C–C bonds

  转移氢化和借用氢反应的出现为以以前无法想象的方式操作简单的醇铺平了道路，并避免了对氢气的需求。类似地，转移烃基化可以大大提高叔醇的多功能性。然而，由于与未活化的CC键的催化裂解有关的挑战，该反应仍未得到探索。在本文中，我们报道了铑（I）催化的穿梭芳基化反应，通过氧化还原中性β-碳消除机制，在未应变的三芳基醇中裂解C（sp 2）-C（sp 3）键。使用良性醇作为潜在的C，实现了从叔醇到酮的取代（杂）芳基的选择性转移烃基化-亲核试剂。所有初步的机械实验都支持可逆的β-碳消除/迁移插入机制。在更广泛的背景下，这种新颖的反应性为催化叔醇的操作提供了新的平台。

  日期：2015.1.16

  A mild, efficient, and low-temperature palladium-catalyzed cyanation of (hetero)aryl halides and triflates is reported. Previous palladium-catalyzed cyanations of (hetero)aryl halides have required higher temperatures to achieve good catalytic activity. This current reaction allows the cyanation of a general scope of (hetero)aryl halides and triflates at 2–5 mol % catalyst loadings with temperatures
