An unprecedented aryl-to-vinyl 1,4-nickel/hydride shift process with further subsequent selective reductive cross-coupling with a wide variety of electrophiles has been developed. This 1,4-nickel migration/reductive coupling sequence provides a facile access to diverse alkenyl C−H-functionalized products under mild conditions and with overall good selectivity.

Under an oxygen umbrella: The Pd‐catalyzed aerobic oxidativecoupling of benzenederivatives with acrylates provides an efficient and atom‐economical route to cinnamamides (see scheme). Readily available starting materials are used and molecular oxygen serves as the sole oxidant. By using this system, the chemoselectiveoxidativecouplingreaction can provide either monoarylation or diarylation products
