Only a few sterically crowded ligands promote palladium-catalyzed, selective monoarylations of ammonia and hydrazine. We herein demonstrate that the formation of palladium precatalysts bearing such ligands is the limiting factor in these reactions, and we present bench-stable, Pd-methylnaphthyl (MeNAP)-tBuBrettPhos complexes as effective catalysts. X-ray and spectroscopic analyses have revealed that
