  2. Asymmetric hydrogenation of vinyl alcohols.
  3. Catalyst used for the asymmetric hydrogenation of enol phosphonates.
  4. Asymmetric hydrogenation of allylic alcohols.
  5. Ligand for the catalytic asymmetric [4+1] cycloaddition of vinylallenes with CO.
  6. Ligand for the Rh-catalyzed asymmetric enyne cycloisomerization.
  7. Catalytic enantioselective addition of dialkylzinc to N-Diphenylphosphinoylimines.
  8. Palladium-catalyzed asymmetric phosphination.
  9. Palladium-catalyzed asymmetric hydrogenation of carbonyls.
  10. Palladium-catalyzed 1,4 arylation of α, β-unsaturated ketones.
  11. Asymmetric, Ir-catalyzed, [2+2+2] cycloaddition.
  12. Asymmertric palladium-catalyzed synthesis of 2-methyl-indolines via C–H activation.
  13. Copper-catalyzed monoborylation of 1,3-Dienes.
  14. Rhodium-catalyzed enantioselective transmetalation.
  15. CuH-catalyzed hydroamination of styrenes.
