Significantly Improved Method for the Pd‐Catalyzed Coupling of Phenols with Aryl Halides: Understanding Ligand Effects

A variety of diaryl ethers were synthesized by the Pd-catalyzed reaction of (hetero)aryl halides and phenols. These reactions were achieved through the use of two new di-tert-butylphosphino biaryl ligands that overcome several limitations of previously described methods.
