In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 29841-69-8, name is (1S,2S)-(-)-1,2-Diphenylethylenediamine, introducing its new discovery. Quality Control of: (1S,2S)-(-)-1,2-Diphenylethylenediamine
The present invention relates to catalytic materials for hydrogenation or asymmetric hydrogenation. In particular, the invention relates to iron (II) complexes containing unsymmetrical tetradentate diphosphine (PNN’P) ligands with two different nitrogen donor groups useful for catalytic transfer hydrogenation or asymmetric transfer hydrogenation of ketones, aldehydes and imines.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 29841-69-8 is helpful to your research. Quality Control of: (1S,2S)-(-)-1,2-Diphenylethylenediamine
