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, 1271-19-8, name is Titanocenedichloride, introducing its new discovery. category: catalyst-ligand
Reaction of titanocene and zirconocene dichloride with ethyl pyruvate aroylhydrazone (viz., ethyl pyruvate picolinoylhydrazone (EPPHyH), ethyl pyruvate furanoylhydrazone (EPFHyH) and ethyl pyruvate thiophenylhydrazone (EPTPHyH) yield complexes of the type CP2M(L)nCl2-n (where M = Ti or Yr, n = 1 or 2 and L = ethyl pyruate aroylhydrazone anion). The complexeshave been characterized on the basis of elemental analyses, IR, PMR, (1 3)C NMR and electronic spectra. The magnetic susceptibility data indicate the complexes to be diamagnetic.
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 1271-19-8 is helpful to your research. category: catalyst-ligand
