摘要：

The asymmetric arylation of N-tosylimines with arylboronic acids was realized by using chiral cationic C-2-symmetric N-heterocyclic carbene (NHC) Pd2+ diaquo complex 5b as the catalyst in combination with 1.0 equiv of K3PO4 center dot 3H(2)O in THF at 4 degrees C in the presence of powdered 4 angstrom MS to afford the corresponding adducts in excellent yields (up to 99%) and good to high enantioselectivities (up to 94% ee).
