Abstract

The development of palladium-catalyzed cross-coupling reactions has revolutionized the synthesis of organic molecules on both bench-top and industrial scales. While significant research effort has been directed toward evaluating how modifying various reaction parameters can influence the outcome of a given cross-coupling reaction, the design and implementation of novel ancillary ligand frameworks has played a particularly important role in advancing the state-of-the-art. This Review seeks to highlight notable examples from the recent chemical literature, in which newly developed ancillary ligands have enabled more challenging substrate transformations to be addressed with greater selectivity and/or under increasingly mild conditions. Throughout, the importance and subtlety of ligand effects in palladium-catalyzed cross-coupling reactions are described, in an effort to inspire further development and understanding within the field of ancillary ligand design.
