Palladium-catalyzed direct olefination of urea derivatives with n-butyl acrylate by C-H bond activation under mild reaction conditions.

Pd(II)-catalyzed aromatic C-H bond activation using urea as a directing group was achieved in a p-TsOH/AcOH medium under mild reaction conditions. The direct olefination products of various urea derivatives were produced from aryl urea derivatives and butyl acrylate in moderate to good yields.
