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, 3471-31-6, name is 2-(5-Methoxy-1H-indol-3-yl)acetic acid, introducing its new discovery. Formula: C11H11NO3
A high-yielding, temperature switchable divergent approach towards the synthesis of either spiro-indolenines or quinolines is described, starting from easily available indolyl ynones. The application of TFA at rt promotes the dearomatization of the indole, resulting in the formation of the spiro-indolenine, while at higher temperature, rearrangement results in the formation of the quinoline.
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 3471-31-6 is helpful to your research. Formula: C11H11NO3
