Buchwald Ligands

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.
