nanoparticles efficiently catalyzed the C–S cross coupling of aryl and alkyl thiols with aryl halides in the absence of ligands on water under mild conditions. A wide range of diaryl sulfides and aryl alkyl sulfides are synthesized in good to excellent yields utilizing this protocol. This procedure is particularly noteworthy given its mild conditions, avoiding the undesired formation of disulfides through
在不存在配体的情况下,CuI纳米颗粒可有效地催化芳基和烷基硫醇与芳基卤化物的C–S交叉偶联 水在温和的条件下。利用该方案,以良好至优异的产率合成了多种二芳基硫醚和芳基烷基硫醚。考虑到其温和的条件,该程序特别值得注意,可避免通过硫醇的氧化而形成不希望的二硫化物。描述了催化剂的回收和成功再利用。此外,提出了双芳基化产物的定向合成。
