temperature, and solvent switching. These transformations feature a simple protocol, broad functional group tolerance, high selectivity, and good to excellent yields. It is noteworthy that these reactions represent the first examples of the application of the selective Chan-Lam coupling.
开发了一种有效的Chan-Lam型方法,用于选择性合成S-芳基苯并咪唑和N,S-二芳基苯并咪唑。通过改变催化剂Cu(OAc)2·H 2 O的量,温度和溶剂转换来控制选择性。这些转化具有简单的操作流程,宽泛的官能团耐受性,高选择性以及优良的收率。值得注意的是,这些反应代表了选择性Chan-Lam偶联应用的第一个例子。
