A robust and practical protocol for preparing alkyl aryl ethers has been developed, which relies on using two types of ligands to promote Cu-catalyzed alkoxylation of (hetero)aryl halides. The reaction scope is very general for a variety of coupling partners, particularly for challenging secondary alcohols and (hetero)aryl chlorides. In case of coupling with aryl chlorides and bromides, two oxalic
已经开发了一种用于制备烷基芳基醚的稳健实用的方案,该方案依赖于使用两种类型的配体来促进 Cu 催化的(杂)芳基卤化物的烷氧基化。反应范围非常适用于各种偶联伙伴,尤其是具有挑战性的仲醇和(杂)芳基氯。在与芳基氯化物和溴化物偶联的情况下,两个草酸二酰胺作为强大的配体。叔丁醇首先被证明是铜催化偶联反应的配体,导致芳基碘化物在室温下完成烷氧基化。此外,许多碳水化合物衍生物适用于该偶联反应,以 29-98% 的产率提供相应的碳水化合物-芳基醚。

Forging a bond: An efficient, general palladium catalyst for CObond‐forming reactions of secondary and primaryalcohols with a range of aryl halides has been developed using the ligand 1. Heteroaryl halides, and for the first time, electron‐rich aryl halides can be coupled with secondaryalcohols. A diverse set of substrate combinations are possible with just a singleligand, thus obviating the need
形成键:使用配体1开发了一种高效、通用的钯催化剂,用于仲醇和伯醇与一系列芳基卤化物的C O 键形成反应。杂芳基卤化物和富电子芳基卤化物首次可以与仲醇偶联。只需一个配体即可实现多种底物组合,因此无需调查多个配体。
