应用

(S)-P-Phos can be used as a ligand:
  • In the asymmetic hydrogenation reactions.
  • For the preparation of chiral ketone functionalized polymers by copolymerization reaction.
  • To synthesize chiral alkynes by asymmetric hydroalkynylation of nonpolar alkenes or norbornadienes using iridium catalyst.
  • In the selective allylic alkylation of indoles using palladium catalyst.

Ligand employed in the asymmetic hydrogenation of ß-keto esters, 2-arylacrylates, aryl ketones , and other substrates.
