| Abstract
| - A new planar-chiral bidentate phosphaferrocene ligand (2) has been synthesized and structurallycharacterized. The derived rhodium complex, [Rh(cod)(2)]BF4, serves as an effective catalyst forasymmetric isomerizations of allylic alcohols to aldehydes, furnishing improved yields, scope, andenantioselectivities relative to previously reported methods. The catalyst is air-stable and can berecovered at the end of the reaction. Mechanistic studies establish that the isomerization proceedsvia an intramolecular 1,3-hydrogen migration and that the catalyst differentiates between theenantiotopic C1 hydrogens.
