Catalysts with a bite : Chiral Pd II complexes were prepared with tridentate N‐heterocyclic carbene amidate alkoxide ligands. Dimeric and monomeric forms were mutually convertible by acid or base treatment (see scheme). The catalysts promote asymmetric Heck reactions efficiently, offering high enantioselectivities far superior to those of existing methods.
