An efficient and convenient bimetallic MnF2/CuI catalyst in combination with trans-1,2-diaminocyclohexane has been developed for the cross-coupling of nitrogen heterocycles with aryl halides in water at moderate temperature. A variety of nitrogen nucleophiles including pyrazole, 7-azaindole, indazole, indole, pyrrole and imidazole afforded the corresponding products in moderate to good yields (up to
已经开发了一种有效且方便的双金属MnF 2 / CuI催化剂与反式-1,2-二氨基环己烷的组合,用于在中等温度下氮杂环与芳基卤化物的交叉偶联。在所述芳基化条件下,包括吡唑,7-氮杂吲哚,吲唑,吲哚,吡咯和咪唑在内的各种氮亲核试剂以中等至良好的收率(最高达94%)提供了相应的产物。
