(R)-BINAP is the enantiopure (R)-enantiomer of 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl, supplied as a white to off-white crystalline powder at 98% purity. The molecule combines the axial chirality of its binaphthyl backbone with two diphenylphosphino donor groups, which gives it strong chelating ability and high stereodiscrimination once coordinated to palladium, ruthenium, rhodium or iridium. This combination has made it
(S)-BINAP is the enantiopure (S)-enantiomer of 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl, a white to light yellow crystalline powder of 98% purity. Its rigid binaphthyl framework fixes the two diphenylphosphine units in a defined helical arrangement, so metal complexes formed with it favour one face of a prochiral substrate and give the opposite configuration to the (R)-form. Because the two
This iridium(I) complex, commonly known as Crabtree’s catalyst, contains a cyclooctadiene ligand, a tricyclohexylphosphine ligand and a pyridine ligand, with hexafluorophosphate as counterion. The well-defined coordination environment provides high regioselectivity in hydrogenation and related transformations.
