An efficient procedure for palladium-catalyzedcoupling reactions of (hetero)aryl bromides and chlorides with primary aliphatic alcohols has been developed. Key to the success is the synthesis and exploitation of the novel bulky di-1-adamantyl-substituted bipyrazolylphosphine ligand L6. Reaction of aryl halides including activated, nonactivated, and (hetero)aryl bromides as well as arylchlorides with

achieved through the cleavage of the sp2 CO bond of aryl/alkenyl ethers catalyzed by a nickel complex, and by using Grignard reagents as nucleophiles (see scheme). This method displays a broad substrate scope and leads to good to excellent yields of the aryl–aryl or alkenyl–aryl cross‐coupling products.

substrates of low reactivity such as aryl fluorides. Because of ease of synthesis and low molecular weight, the conjugate base of triethylurea (TEU–) was of primary focus. Visible spectroscopy and reactivity data are consistent with the hypothesis that the same complex is being formed when SmI2 is combined with either 2 or 4 equiv of TEU–, in spite of the greater reactivity of SmI2/4 TEU– with some alkyl

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。
