Cu-catalyzed direct C–H amination of 2-alkylazaarenes with azodicarboxylates via nucleophilic addition
摘要:
An efficient Cu-catalyzed C-H amination of 2-alkylazaarenes with azodicarboxylates has been developed through nucleophilic addition of sp(3)C-H bond to unsaturated nitrogen-nitrogen double bond. It provides an easy access to azaarene-containing hydrazines from simple and easily available starting materials. (c) 2012 Elsevier Ltd. All rights reserved.
