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, 15861-24-2, name is Indole-5-carbonitrile, introducing its new discovery. Application In Synthesis of Indole-5-carbonitrile
(Chemical Equation Presented). An efficient synthesis of the potent KDR inhibitor 3-[5-[[4-(methylsulfonyl)-1-piperazinyl]methyl]-1H-indole-2-yl] quinolin-2(1H)-one (1) is described. The process features a noncryogenic indole boronation and a dicyclohexylamine-mediated Suzuki coupling.
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 15861-24-2 is helpful to your research. Quality Control of: Indole-5-carbonitrile
