The C–S coupling reaction of aryl iodides with thiols was achieved at 110 °C in DMF/dioxane (V/V, 1:9) in the presence of a tridentate hydroxy-functionalised MCM-41-immobilised copper(I) complex [MCM-41-3OH-CuI] with Cs2CO3 as base to afford a variety of diaryl sulfides in good to excellent yields. The MCM-41-3OH-CuI catalyst can be easily recovered by a simple filtration and reused for at least six
在三齿羟基官能化的 MCM-41 固定化铜 (I) 络合物存在下,芳基碘化物与硫醇的 C-S 偶联反应是在 110 °C 下在 DMF/二恶烷(V/V,1:9)中实现的。 MCM-41-3OH-CuI] 以 Cs2CO3 为碱,以良好到极好的收率提供各种二芳基硫化物。MCM-41-3OH-CuI 催化剂可以通过简单的过滤轻松回收并重复使用至少六次而不会显着降低活性。
