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. Recommanded Product: 18531-99-2
A series of tri-O-alkylated inherently chiral fluorescent calix[4]crowns in the cone conformations and a series of tetra-O-alkylated inherently chiral fluorescent calix[4]crowns in the partial cone conformations have been synthesized. By condensing with chiral auxiliary (S)-BINOL, the resulting diastereomers could be separated via preparative TLC. We found that the size of the crown moiety effected the separation of the diastereomers. Further, removal of the BINOL unit by hydrolysis furnished pairs of enantiomers with optical purity. Moreover, we found that a tetra-O-alkylated inherently chiral fluorescent calix[4]crown-6 in the partial cone conformation 6c showed considerable enantioselective recognition capability towards chiral leucinol.
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. Recommanded Product: 18531-99-2
