dienes by Pd(II)-catalyzed direct olefination of unactivated alkenes with allylicesters and acrylates via vinylic C–H activation. Various aryl and heteroaryl alkenes as well as aliphatic alkenes all give the desired linear 1,3-butadienes with retention of the traditionalleavinggroups such as OAc and other carboxylic acid estergroups.
