Desymmetrization is an essential method for the synthesis of chiral compounds, particularly chiral biaryls. We have developed an enantioselectivesynthesis of axially chiral biaryls by desymmetrization using C(sp3)–H activation catalyzed by chiral palladium phosphate. Mechanistic studies show that C–H activation is the rate- and enantiomer-determining step. To the best of our knowledge, this is the
