Functionalization of Amides via Copper-Catalyzed Oxyalkylation of Vinylarenes and Decarboxylative Alkenylation of sp3 C–H
摘要:
An efficient protocol was developed to prepare a series of derivatives from amides by copper-catalyzed oxyalkylation of vinylarenes and decarboxylative alkenylation of sp(3) C-H. This method is simple, practical, and inexpensive.

enables selective incorporation of alkenyl, alkynyl and allyl functional groups into the C(sp3)–H bond under green reaction conditions is developed. The process is based on the catalytic formation of α-alkoxyl/α-amidyl radicals via the homolytic activation of the C(sp3)–H bond of ethers/amides with a catalytic amount of diarylketone in the presence of a household fluorescent light bulb. This simple reaction
