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, 3189-13-7, name is 6-Methoxyindole, introducing its new discovery. SDS of cas: 3189-13-7
The first Pd-catalyzed direct C-H acylation of indoles at the C4 position with alpha-oxocarboxylic acids using a ketone directing group is described. This reaction exhibits high regioselectivity with the tolerance of a wide scope of functional groups to afford diverse acylated indoles in moderate-to-good yields. The control experiments evidence the generation of acyl radicals via K2S2O8 promoted decarboxylation of alpha-oxocarboxylic acids and the involvement of a PdII/PdIV catalytic cycle. Importantly, the synthetically useful selectivity observed might be applied to prepare indole derivatives with anti-tumor activity as tubulin inhibitors.
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 3189-13-7 is helpful to your research. SDS of cas: 3189-13-7
