## Abstract Palladium‐catalyzed cross‐coupling of bipyridine __N,N′__‐dioxide 6,6′‐dichloride (__R__~__nap__~__,R__~__pyr__~)‐**1** with the aryl Grignard reagents opened a new approach to axially chiral bipyridine __N,N′‐__dioxides (__R__)‐**2** bearing a variety of aryl groups at the 6 and 6′ pos
