  RuCl₃-Catalyzed Regioselective Diarylation with Aryl Tosylates via C-H Activation

  摘要：

  The direct arylation of arylpyridines with aryl tosylates was carried out smoothly in the presence of 2.5mol% RuCl3 using MesCOOH as crucial promoter to generate biarylated products. The method is simple, efficient, safe, and regioselective, can be performed in the absence of expensive ligands, and does not require any precautions with regard to the exclusion of air and moisture. The biarylated products were obtained in good yields. Supplemental materials are available for this article.

  The direct arylation of aryl iodides with 2-phenylpyr­idines and related substrates was carried out smoothly in the presence of 5 mol% RuCl3 using benzoyl peroxide as a promoter to generate biarylated products in high yields. The method is simple, efficient, and regioselective, and employs only commercially available reagents.

  在5 mol%的RuCl3存在下，使用苯甲酰过氧化物作为促进剂，顺利地实现了芳香碘化物与2-苯基吡啶及相关底物的直接芳烃化反应，生成了高产率的二芳基化产品。该方法简单、高效且具有区域选择性，且仅使用商业上可获得的试剂。
