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. HPLC of Formula: C14H16N2
Two diastereoisomeric ditopic ligands have been synthesised by linking (SSS)-hepatadenate triamide derivative of cyclen with a central (SS)- or (SR)- 1, 2-diphenyl-1, 2-diaminoethane derivative. Complexes of selected Ln III ions (Ln = Eu, Tb, Yb) have been characterized and circularly polarised luminescence spectra of the Eu systems revealed significant differences, consistent with a change in overall complex chirality associated with the local helicity at the metal centre. Stepwise binding constants for the formation of 1:1 and 2:1 ternary adducts with (S)-lactate and (S)-O-phospho-tyrosine have been determined, by least-squares analysis of spectral titration data, and emission and 1H NMR spectroscopic data compared with the mononuclear analogue.
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. HPLC of Formula: C14H16N2
