derivative. So far, no synthetic pathway has been found to avoid this intramolecular reaction. Herein we report the first general and external‐ligand‐free palladium‐catalyzed phosphination reaction that allows the synthesis of a wide variety of substituted ortho,ortho′‐bis(diphenylphosphino)biphenyls. With the aim of illustrating the scope and efficiency of this methodology, we applied it to the establishment
