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, 19012-03-4, name is 1-Methyl-1H-indole-3-carbaldehyde, introducing its new discovery. Formula: C10H9NO
The present work describes an expedient approach for the direct conversion of indole-3-carboxaldehyde to 3-chlorooxindoles using a simple sustainable synthetic method. From an environmental perspective, a combination of NaCl/oxone in a CH3CN?:?H2O (1?:?1) system was developed for direct oxidative chlorination of a wide array of indole derivatives. This chlorination strategy is more viable, remarkably cheaper and provides easy access to potential 3-chlorooxindoles. In addition, this environmentally benign method can also be applicable for constructing isatin derivatives in good yields.
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 19012-03-4 is helpful to your research. Formula: C10H9NO
