This paper describes the synthesis and characterization of silver, copper and gold complexes supported by several amino-NHC ligands with different amino side arms. The transmetallation process using silver-NHC complexes can be used to prepare amino-NHC copper and gold complexes easily in high yield. In addition, the catalytic activities of copper complexes are examined for arylation of caffeine via
本文描述了几种具有不同氨基侧链的氨基-NHC配体所支持的银,铜和金配合物的合成和表征。使用银-NHC配合物的金属转移过程可用于轻松地以高收率制备氨基-NHC铜和金配合物。此外,还检查了铜配合物的催化活性,以通过C–H键活化咖啡因的芳基化。
