phosphine ligands elaborated on the binepine scaffold is described. Their application in the Pd-catalyzedintramolecularasymmetricα-arylation of aldehydes and the intermolecular asymmetric γ-arylation of α,β-unsaturated aldehydes provides a mean of validating the design of these ligands. For the first reaction, excellent reactivities have been obtained while only modest enantioselectivities were measured
