Palladium-catalyzed amination reactions of aryl halides have undergone rapid development in the last 12 years, largely driven by the implementation of new classes of ligands. Biaryl phosphanes have proven to provide especially active catalysts in this context. This Review discusses

The Pd-catalyzed C–N bond formation has become an important synthetic reaction in the past 20 years. Several research groups have investigated this reaction and developed very versatile catalysts. Buchwald and coworkers have been very active in synthesizing and developing a portfolio of phosphine ligands for this transformation and other cross-coupling reactions.

Buchwald phosphine ligands for C-C, C-N, and C-O bond formation.
