A CuI-catalyzed coupling reaction of aryliodides and sulfur powder takes place in the presence of K2CO3 at 90 °C. The coupling mixture is directly treated with NaBH4 or triphenylphosphine to afford aryl thiols in good to excellent yields. A wide range of substituted aryl thiols that bear methoxy, hydroxyl, carboxylate, amido, keto, bromo, and fluoro groups can be assembled through this procedure.
CuI催化的芳基碘化物和硫粉的偶联反应在90°C的K 2 CO 3存在下进行。偶联混合物直接用NaBH 4或三苯基膦处理,以良好或优异的收率得到芳基硫醇。可以通过该程序组装具有甲氧基,羟基,羧酸酯基,酰胺基,酮基,溴基和氟基的各种各样的取代的芳基硫醇。
