We describe a new method for the stereoselective synthesis of (Z)-1,2-dithio-1-alkenes via copper-catalyzed cross-coupling of (Z)-2-bromovinyl sulfides and thiols. The desired products are obtained in good to excellent yields. The double bond geometry of the starting (Z)-2-bromovinyl sulfides is retained under these reaction conditions.
我们描述了一种通过铜催化的(Z)-2-溴乙烯硫化物和硫醇的交叉耦合反应来实现(Z)-1,2-二硫-1-烯烃的立体选择性合成的新方法。所需的产物以良好至优秀的产率获得。在这种反应条件下,起始的(Z)-2-溴乙烯硫化物的双键几何结构得以保留。
