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, 18531-94-7, name is (R)-[1,1′-Binaphthalene]-2,2′-diol, introducing its new discovery. name: (R)-[1,1′-Binaphthalene]-2,2′-diol
Ortho-Acidic aromatic thiols as efficient catalysts of intramolecular Morita-Baylis-Hillman and Rauhut-Currier reactions
ortho-Mercaptobenzoic acid and ortho-mercaptophenols were discovered as efficient thiol catalysts of both the intramolecular Morita-Baylis-Hillman (MBH) and Rauhut-Currier (RC) reaction. High reaction rates were achieved under mildly basic, aqueous conditions. The unprecedented catalytic activity of these protic nucleophiles could originate from a Br¡ãnsted acid induced destabilization of intermediate thioethers and thus represent a unique mechanism of multifunctional Lewis base catalysis.
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 18531-94-7 is helpful to your research. name: (R)-[1,1′-Binaphthalene]-2,2′-diol
