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. Product Details of 1271-19-8
A comparative study by EPR is made on the electrolytic reduction of Cp2MX2, Cp2M(CH3)2, (Cp = eta5-C5H5, cyclopentadienyl ligand; M = Ti, Zr; X = Cl, Br) and Ind2Ti(CH3)2 (Ind = eta5-C9H7, indenyl ligand) in the presence of phosphines. In the case of the dihalides, the monohalo(phosphines) were characterized. In the case of the dimethyl compounds, Cp2M(CH3)(PMe3) and Ind2Ti(CH3)(PMe3) were identified at 230 K from their EPR spectra. At room temperature and for M = Ti, intramolecular rearrangement takes place to yield the presumably chelated dimethylphosphinomethyl compound Cp2Ti(III)CH2PMe2 while Ind2Ti(CH3)(PMe3) remains stable.
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. Product Details of 1271-19-8
