Application

Developed in the Engle lab, this 2,2′-bipyridylamide (PPA) is a pincer-like, removable tridentate directing group that stabilizes 6-membered palladacycles for olefin functionalization. Together with similar ligand PAQ (901250), researchers demonstrated regioselective remote hydrocarbofunctionalization of alkene-containing substrate classes (e.g. 4-pentenoic acids, allylic alcohols, homoallyl amines, bis-homoallylamines) using Pd(II) catalysis.
