highly effective C−O coupling reaction of (hetero)aryl electrophiles with primary and secondary alcohols is reported. Catalyzed by a NiII‐arylcomplex under long‐wave UV (390–395 nm) irradiation in the presence of a soluble amine base without any additional photosensitizer, the reaction enables the etherification of aryl bromides and arylchlorides as well as sulfonates with a wide range of primary
据报道,(杂)芳基亲电试剂与伯醇和仲醇的高效C-O偶联反应。在可溶性胺碱的存在下,在没有任何其他光敏剂的情况下,在长波紫外线(390–395 nm)辐射下,由Ni II-芳基络合物催化,该反应可以使芳基溴化物和芳基氯化物以及磺酸盐与多种伯和仲脂族醇,可提供合成上重要的醚。分子内CO偶联也是可能的。该反应似乎通过Ni I -Ni III催化循环进行。
cross-coupling of aryl halides with primary and secondary alcohols, without the need for photo- or electrocatalysis. The protocol is simple and has a wide substrate scope, particularly for challenging electron-rich aryl halides. Additionally, this methodology has been successfully applied to the late-stage functionalization of drugs and natural products, as well as the synthesis of pharmaceuticals such
