A chelation-assistedpalladium-catalyzed acyloxylation of the sp3 C–H bond of benzyl by carboxylic acid is described, which employs PhI(OAc)2 as a stoichiometric oxidant. The procedure tolerates a series of functional groups, such as methoxyl, chloro, bromo, iodo, vinyl, formyl, phenolic hydroxyl, nitro, and cyano groups, providing the acyloxylation products in moderate to good yields.
palladium-catalyzed selective activation of CH bonds is of great importance for the construction of diverse bioactive molecules. Herein, monodisperse CuPd alloy nanoparticles supported on reduced grapheneoxide have been used as high efficient and recyclable catalyst for C(sp3)−H acyloxylation of 8-methylquinolines in good yields under mild conditions. The developed catalytic system proceeds with low palladium
