A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a Article,once mentioned of 14187-32-7, category: chiral-catalyst
Sodium and potassium phenoxide, in the presence of one equivalent of dicyclohexano-18-crown-6(cis-anti-cis isomer) and dibenzo-18-crown-6, from complexes that have a ratio of 1:1:1 (crown:salt:phenol) in ethereal solvents containing excess phenol.On the other hand, complexes having 1:1:2 ratios (crown:salt:phenol) are obtained under the same conditions when the macrocycle is 18-crown-6 or dicyclohexano-18-crown-6(cis-syn-cis isomer).When only one equivalent of phenol is present, then 1:1:1 complexes are obtained with 18-crown-6 and dicyclohexano-18-crown-6(cis-syn-cis isomer).No complexes containing only the metal salts were isolated from these solutions.The infrared spectral data obtained from the complexes show that the phenol hydroxyl hydrogens in the complexes form either strong hydrogen bonds.The nuclear magnetic resonance chemical shifts of the phenol protons in the complexes have been obtained from deuterated dimethoxyethane solutions.Comparisons are made with the chemical shifts of the phenol hydroxyl protons obtained from the corresponding solutions containing only the equivalent salt/phenol solutions.
