The efficient and mild copper-catalyzed synthesis of unsymmetrical diorganyl chalcogenides under ligand- and solvent-free conditions is described. The cross-coupling reaction was performed using aryl boric acids and 0.5 equiv. of diorganyl dichalcogenides (Te/Se/S) in the presence of 3 mol % of CuI and 3 equiv. of DMSO, under microwave irradiation. This new protocol allowed the preparation of several unsymmetrical diorganyl chalcogenides in good to excellent yields.
本文描述了在无配体和无溶剂条件下高效温和的铜催化不对称二有机硫属化合物的合成方法。交叉偶联反应是在3 mol%的碘化亚铜和3当量二甲基亚砜存在下，使用芳基硼酸和0.5当量的二有机二硫属化合物（碲/硒/硫），在微波辐射下进行的。这种新方法能够以良好至优异的产率制备多种不对称二有机硫属化合物。
