Enantioselective palladium-catalyzed arylation of N-tosylarylimines with arylboronic acids using a chiral 2,2′-bipyridine ligand

An enantioselective palladium-catalyzed arylation of N-tosylarylimines with arylboronic acids was developed by using an axially chiral 2,2′-bipyridine ligand C3-ACBP, affording chiral diarylmethamines with up to 94% ee under exogenous-base-free conditions.
