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, 29841-69-8, name is (1S,2S)-(-)-1,2-Diphenylethylenediamine, introducing its new discovery. Computed Properties of C14H16N2
Titanium and zirconium complexes of bispicolinic amides catalyze the ring opening of cyclohexene oxide with trimethylsilyl azide as nucleophile.The product, 1-azido-2-trimethylsilyloxycyclohexane, was obtained in up to 71percent enantioselectivity when a catalyst prepared from (S,S)-N,N’-bis(2-pyridinecarboxamide)-1,2-diphenylethane and zirconium tetra-t-butoxide was employed under optimum conditions, which included the addition of a small amount of diethylamine in the catalyst preparation step.The nature of the catalyst is still unknown, but it seems probable that oligomeric metal species are involved.
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 29841-69-8 is helpful to your research. Computed Properties of C14H16N2
