Under the optimizedconditions, the reactions between primary alkylamines and aryl iodides could beperformed successfully to afford the products with high yields generally using thenew catalyzed systems based on 51, and many of these transformations are themost efficient up to now. Secondary amines could also be coupled with aryliodides, however, the yields were slightly lower than primary amines. Besidesalkylamines, N-H heterocycles were also suitable substrates. In addition, differentamines could be coupled with aryl iodides successfully with moderate to goodyields in solvent-free conditions.
在优化的反应条件下，基于51 的催化体系能使得多种碘代芳烃与一级脂肪胺之间的交叉偶联反应顺利进行，收率普遍较高，其中某些目标产物的收率是目前最高的；二级脂肪胺也能较好地转变成目标产物，然而收率普遍比一级胺要低；除了脂肪胺以外，多种含N-H 杂环化合物也是合适的底物；另外，在无溶剂的条件下，碘代芳烃也能有效地与多种胺类发生偶联反应。
