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, 150-61-8, name is N1,N2-Diphenylethane-1,2-diamine, introducing its new discovery. Quality Control of: N1,N2-Diphenylethane-1,2-diamine
A series of donor- and acceptor-substituted ruthenium cyclopentadienone complexes were synthesized and their catalytic activities towards propargyl alcohols focused on amination reactions have been investigated. It is shown that the substituents of the cyclopentadienone ligand determine the mode of activation of propargyl alcohols by these complexes leading to different central intermediates in catalytic cycles. Catalytic transformations of propargyl alcohols to alpha- or beta-amino ketones, enamino ketones, alpha,beta-unsaturated imines, ketones, alkenes and conjugated enynes could be achieved.

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 150-61-8 is helpful to your research. Quality Control of: N1,N2-Diphenylethane-1,2-diamine
