Abstract

Efficient palladium catalyst systems based on the combination of bench stable biaryl phosphacycles and Pd(OAc)2 are described for Suzuki-Miyaura cross-coupling reactions of aryl bromides and chlorides. Notably, the electronically and sterically diametric biaryl phosphacycles allowed facile coupling of sterically hindered and heterocyclic substrates.
