A catalytic asymmetric addition of arylboronic acids to isatins has been achieved by using chiral cationic C-2-symmetric N-heterocyclic carbene (NHC) Pd2+ cliaqua complexes as the catalysts. The reaction can be performed under convenient conditions to give the corresponding adducts in good to high yields (79-94%) and moderate to excellent enantioselectivities (up to 94% ee) in the presence of LiOAr as the promoter which was generated in situ.
