The use of 3,4,7,8-tetramethyl-1,10-phenanthroline (Me4Phen) as a ligand improves the Cu-catalyzed cross-coupling reactions of aryl iodides and bromides with primary and secondary aliphatic, benzylic, allylic, and propargylic alcohols. Most importantly, by employing this catalyst system, the need to use an excessive quantity of the alcohol coupling partner is alleviated. The relatively mild conditions
使用 3,4,7,8-四甲基-1,10-菲咯啉 (Me 4 Phen) 作为配体改善了 Cu 催化的芳基碘化物和溴化物与伯、仲脂肪族、苄基、烯丙基、和炔丙醇。最重要的是,通过使用这种催化剂体系,可以减轻使用过量醇偶联剂的需要。相对温和的条件、较短的反应时间和适度低的催化剂负载量允许在亲电子和亲核偶联伙伴上容忍多种官能团。
