General description

sold in collaboration with Solvias AG

Application

(S)-1-{(SP)-2-[2-(Diphenylphosphino)phenyl]ferrocenyl}ethylbis[3,5-bis-(trifluoromethyl)phenyl]phosphine can be used:
  • To prepare sulfide-capped triruthenium hydrido clusters containing Walphos ligands, which are employed as catalysts for asymmetric hydrogenation of tiglic acid (trans-2-methyl-2-butenoic acid).
  • As a ligand in the reductive allylic alkylation of unsaturated carbonyl compounds using Pd catalyst.
