A ligand-controlled branch-selective allylic C-H carboxylation through Pd catalysis is described. The developed catalytic system, which consists of Pd(OAc)2, sulfoxide-oxazoline (sox) as a ligand and benzoquinone as an oxidant, couples terminal alkenes and carboxylic acids to furnish the corresponding branched allylic esters with high regioselectivity.
