  Investigating the Dearomative Rearrangement of Biaryl Phosphine-Ligated Pd(II) Complexes

  摘要：

  A series of monoligated L.Pd-II(Ar)X complexes (L = dialkyl biaryl phosphine) have been prepared and studied in an effort to better understand an unusual dearomative rearrangement previously documented in these systems. Experimental and theoretical evidence suggest a concerted process involving the unprecedented Pd-II-mediated insertion of an aryl group into an unactivated arene.

  单膦配体允许钯催化与仲醇和伯醇形成分子间 C2O 键

  摘要：

  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。

  Forging a bond: An efficient, general palladium catalyst for CO bond‐forming reactions of secondary and primary alcohols 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 secondary alcohols. A diverse set of substrate combinations are possible with just a single ligand, thus obviating the need
