C2-Symmetric ligands


In homogeneous catalysis, a C2-symmetric ligands usually describes bidentate ligands that are dissymmetric but not asymmetric by virtue of their C2-symmetry. Such ligands have proven valuable in catalysis.[1] With C2 symmetry, C2-symmetric ligands limit the number of possible reaction pathways and thereby increase enantioselectivity, at least relative to asymmetrical analogues. Chiral ligands combine with metals to form chiral catalyst, which engages in a chemical reaction in which chirality is transfer to the reaction product. C2 symmetric ligands are a subset of chiral ligands.
