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。

A process for producing aromatic polyether ketones and polythioether ketones, which comprises reacting aromatic ethers or thioethers represented by the general formula:
where each of R1 to R12 is a hydrogen atom, a halogen atom, a hydrocarbon group or an alkoxy group, n is an integer of 0 to 5, and X is an oxygen atom or a sulfur atom, with phosgene in aprotic solvent having a dielectric constant of lower than 20 and a dipole moment of lower than 3.0 in the presence of anhydrous halides of metals of Group III in the periodic table as a catalyst.
Selective bis-sulfenylation reactions of aryl dihalides have been achieved by copper-catalyzed C–S coupling reactions under mild conditions of refluxing EtOH (80 °C).
