Application

(R)-(−)-1,1′-Bi-2-naphthol bis(trifluoromethanesulfonate) can be used:
  • In the synthesis of heterobidentate ligands for asymmetric catalysis.
  • To prepare 2-(diphenylphosphino)-2′-alkoxy-1,1′-binaphthyls by reacting with bis(aryl) phosphonic acids.
  • As a starting material for the synthesis of binaphthyl based rhodium catalysts used in the hydrogenation of styrene.
