Top of the P-O-Ps: Stabilization of a cationic rhodium catalyst with the hemilabile P-O-P ligand dpephos allows efficient intermolecular hydroacylation of challenging substrates (see scheme). Structural studies have established the role of the coordination of the oxygen atom, and a catalytically competent acyl–hydridorhodium intermediate was fully characterized.
