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, 18531-99-2, name is (S)-[1,1′-Binaphthalene]-2,2′-diol, introducing its new discovery. Safety of (S)-[1,1′-Binaphthalene]-2,2′-diol
Minor groove thiosemicarbazone functionalized (S)-BINOL 1 has been synthesized starting from (S)-BINOL; these new thiosemicarbazone functionalized (S)-BINOL molecules introduce new opportunities in the field of chiral recognition and Fe(III) sensing. The developed sensor can serve as a turn off sensor for Fe(III) with high selectivity among metal ions tested. The in situ generated Fe(III) complex of 1 exhibit remarkable fluorescent chiral discrimination toward unmodified alpha-amino acids via a ligand displacement mechanism.
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 18531-99-2 is helpful to your research. Safety of (S)-[1,1′-Binaphthalene]-2,2′-diol
