The Ullmann-type coupling reaction of vinyl bromides and activated methylene compounds under CuI/L-proline in DMSO, at 90 °C in the presence of Cs 2 CO 3 gives the corresponding vinyl compounds in moderate to good yields. This is a good method for preparing compounds with multiple functional groups including double bonds, carbonyls, and/or esters.
在 DMSO 中,在 CuI/L-脯氨酸下,在 90 °C 下,在 Cs 2 CO 3 存在下,乙烯基溴化物和活化的亚甲基化合物的 Ullmann 型偶联反应以中等至良好的产率得到相应的乙烯基化合物。这是制备具有多个官能团(包括双键、羰基和/或酯)的化合物的好方法。
