In hydroformylation, phosphorus-based directinggroups have been consistently successful at placing the aldehyde on the carbon proximal to the directinggroup. The design and synthesis of a novel catalyticdirectinggroup are reported that promotes aldehyde formation on the carbon distal relative to the directing functionality. This scaffolding ligand, which operates through a reversible covalent bond
