Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 4254-15-3, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 4254-15-3
SYNPHOS: A new atropisomeric diphosphine ligand. From laboratory-scale synthesis to scale-up development
A new optically active diphosphine ligand, [(5,6),(5?,6?)-bis(ethylenedioxy)biphenyl.2,2?-diyl]bis (diphenylphosphine) (SYNPHOS) has been synthesized. Laboratory-scale synthesis and scale-up development of this ligand are described herein. This new atropisomeric diphosphine was also used in ruthenium-catalyzed asymmetric hydrogenation.
