This work describes the essential radicalpolarityeffects manifested in pursuit of a group transfer radical addition to achieve alkeneaminoallylation. Each open shell intermediate along the proposed mechanistic pathway is steered to preferentially react with only one reagent.

application of hydroformylation to the synthesis of quaternary carbon centers is reported. The synthesis of the highly substituted carbon is achieved by applying a catalyticamount of 1. Ligand 1 serves as a catalyticdirectinggroup by covalently and reversibly binding to both the substrate and catalyst. The intramolecular nature of the directinggroup strategy accelerates the hydroformylation reaction
