WebA sterically bulky ligand, tBuPPh2, affords para-acylated products 3, whereas a sterically less bulky ligand, Me2PPh, provides ortho-acylated products 4. Further, direct substitution product 5 at the benzylic position is not obtained essentially, although such a reaction at the benzylic position is favorable in ordinary nucleophilic substitutions.
