described, in which mono- and difunctionalization of alkenes are selectively achieved. In this reaction with amides, the chemoselectivity toward the functionalization of the C(sp(3))-Hbonds adjacent to the nitrogen atom or the functionalization of the carbonyl C(sp(2))-Hbonds across alkenes relies on the reaction conditions.

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.
Nickel-Catalyzed sp3 C–H Bond Activation from Decarboxylative CrossCoupling of α,β-Unsaturated Carboxylic Acids with Amides
Nickel-catalyzed functionalization of C(sp3)–H bonds adjacent to a nitrogen atom in amides through decarboxylative cross-coupling of α,β-unsaturated carboxylic acids is reported. A possible reaction mechanism is proposed that involves radical intermediate species.
