[Reactions]

  1. Biaryl bisphosphine ligand. The H8-BINAP ligand, as the ruthenium complex, catalyzes hydrogenation of unsaturated carboxylic acids to a higher ee than does BINAP.
  2. The ruthenium catalyzed hydrogenation of aryl propenoic acid to produce the drug Ibuprofen.
  3. Rhodium catalyzed asymmetric regioselective 1,4-addition of arylboronic acids to 3-substituted maleimides.
  4. Ligand for palladium-catalyzed enantioselective hydrogenation of substituted indoles.
  5. Rhodium-catalyzed enantioselective cyclization of γ-alkynylaldehydes with acyl phosphonates.
  6. Enantioselective synthesis of axially chiral 1-arylisoquinolines by Rh-catalyzed [2+2+2] cycloaddition.
  7. Enantioselective synthesis of 2,3-disubstituted indolines through Bronsted acid/Pd-complex-promoted tandem reactions.
