A highly efficient method for the selective formal C–H/C–H cross-coupling of azoles and (hetero)arenes was established through arylsulfonium intermediates under transition-metal catalysis, which produced a variety of 2-(hetero)aryl azoles in good to excellent yields. Advantages of the reaction included mildness, a good functional group tolerance, a wide range of substrates, a high regio- and chemoselectivity
van Leusen reaction, with various aryl iodides is effectively promoted by a system of CuI combined with PPh3 and Na2CO3 as a ligand and a base, respectively, in DMF to produce the corresponding 2,5-diaryloxazoles in good yields.
通过van Leusen反应制得的5-芳基恶唑与各种芳基碘的直接芳基化反应,是通过CuI与PPh 3和Na 2 CO 3分别作为配体和碱在DMF中结合形成的体系有效地促进的。相应的2,5-二芳基恶唑,收率高。

The (hetero)biaryls are fundamental to drug discovery and rapid, general access to these motifs is essential for medicinal chemistry. Herein, a nickelcatalyzed reductive cross-electrophile coupling between heteroaryl iodides and bromides is described. We demonstrated that the reaction is chemoselective, scalable, and amenable to library fashion with an array of scaffolds (45 examples).
