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
The present invention relates to a stereoselective glycosylation for the preparation of 1,3-oxathiolane nucleoside in high yield and high optical purity. The invention specifically relates to a process of the preparation of Lamivudine and Emtricitabine using zirconium (IV) chloride (ZrCl4) as a catalyst in glycosylation.
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
