Phenols are considered as an ideal alternative to aryl halides as coupling partners in cross-coupling reactions. In the present work a copper-catalyzed cross-coupling of phenols with various aromatic and aliphatic amines for the synthesis of secondary aryl amines using dichloroimidazolidinedione (DCID) as a new and efficient activating agent has been developed. Substituted phenols were compatible with the standard reaction conditions. The two proposed mechanisms, which are based on the oxidation addition of copper with Ar-OMCID (MCID: Monochloroimidazolidinedione), are also discussed.

使用二氯咪唑烷二酮 (DCID) 进行酚和胺的新型改性交叉偶联

酚类被认为是芳基卤化物的理想替代品，作为交叉偶联反应中的偶联伙伴。在目前的工作中，使用二氯咪唑烷二酮 (DCID) 作为一种新的有效活化剂，铜催化苯酚与各种芳香族和脂肪族胺的交叉偶联，用于合成仲芳胺。取代酚与标准反应条件相容。还讨论了基于铜与 Ar-OMCID（MCID：单氯咪唑烷二酮）的氧化加成的两种建议机制。
