Cu 2 O powder is a very reactive catalyst for the coupling of thiols to aryl iodides. A variety of functional groups including esters, unprotected amines, alcohols, and heterocycles tolerate the reaction conditions. Moreover, di-ortho-substituted aryl iodides with sterically demanding substrates were also coupled to give the desired aryl thioethers in good to excellent yields.
市售的 Cu 2 O 粉末是一种非常活泼的催化剂,用于将硫醇偶联到芳基碘化物上。包括酯、未保护胺、醇和杂环在内的多种官能团可耐受反应条件。此外,二邻位取代的芳基碘化物与空间要求严格的底物也被偶联,以良好至极好的产率得到所需的芳基硫醚。
