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
environmentally friendly, and ligand-free synthetic protocol for the cross-coupling reaction of aryliodides and thiols using 10 mol % CuI with KF/Al2O3 as the base, in DMF at 110 °C. Using this protocol, we have shown that a variety of aryl sulfides can be synthesized in excellent yields from readily available iodides and thiols.
我们报告了一种温和,方便,环保,无配体的合成方案,用于在110°C的DMF中使用10 mol%CuI与KF / Al 2 O 3为基础的芳基碘化物和硫醇的交叉偶联反应。使用该协议,我们已经表明,可以从易得的碘化物和硫醇中以优异的产率合成多种芳基硫化物。
