Palladium-catalyzed Branch-selective Decarboxylative Allylation Using Ion-paired Ligands

A Pd-catalyzed branch-selective decarboxylative allylation of ketone-derived monosubstituted allylic enol carbonates is reported. The use of an ammonium–phosphine hybrid ligand bearing a non-coordinating anion is crucial for obtaining a branched isomer with high regioselectivity.
