A highly efficient and simple cross-coupling reactions of aryltitanium reagents with -aryl thiosuccinimides for the synthesis of arylsulfide derivatives using Cu(acac) (20 mol%) as catalyst are reported. Under the optimum reaction conditions, the coupling reaction between (hetero)aryltitanium reagents with -aryl thiosuccinimides can be carried out smoothly, 18–93 % isolated yields of arylsulfides were
报道了芳基钛试剂与芳基硫代琥珀酰亚胺的高效、简单的交叉偶联反应,以 Cu(acac) (20 mol%) 作为催化剂合成芳基硫醚衍生物。在最佳反应条件下,(杂)芳基钛试剂与芳基硫代琥珀酰亚胺的偶联反应能够顺利进行,芳基硫醚的分离收率为18%~93%。此外,1-(吡啶-2-基硫基)吡咯烷-2,5-二酮和1-(异丁硫基)吡咯烷-2,5-二酮也能与芳基钛试剂有效配合。此外,广泛的底物范围和典型的克级高效维持使该方案成为合成芳基硫醚衍生物的潜在实用方法。该方法避免了使用昂贵的过渡金属Pd、Ir或Rh、膦配体,操作简单,反应效率高。
