We report a general copper‐catalyzed cross‐coupling of thiols with aryl halides by using N‐aryl‐N′‐alkyl oxalic diamide (L3) or N,N′‐dialkyl oxalic diamide (L5) as the ligand. Both aryl and alkyl thiols can be coupled with unactivated aryl bromides and chlorides to give the desired products in good yields. Furthermore, this system features a broad substrate scope and good tolerance of functional groups
我们通过使用报告与芳基卤硫醇的一般铜-催化的交叉偶联ñ -芳基- N' -烷基草酸二酰胺(L3)或ñ,N' -二烷基二酰胺草酸(L5)作为配体。芳基和烷基硫醇都可以与未活化的芳基溴化物和氯化物偶合,以高收率得到所需的产物。此外,该系统具有广泛的底物范围和对官能团的良好耐受性。重要的是,草酸二酰胺是稳定的,并且可以容易地由市售和廉价的起始原料制备。
