A copper-catalyzed cross-coupling of heterocyclic thiols with aryl iodides is reported. The reaction was carried out in the presence of CuI (5 mol %), 1,10-phenanthroline (10 mol %) and K2CO3 (1.3 equiv) in DMF at 120 °C. A variety of heterocyclic sulfides were prepared in high selectivities and yields.
据报道,铜催化的杂环硫醇与芳基碘化物的交叉偶联。反应在120℃下在CuI(5mol%),1,10-菲咯啉(10mol%)和K 2 CO 3(1.3当量)的存在下在DMF中进行。以高选择性和高产率制备了各种杂环硫化物。
