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, 877-03-2, name is 5-Bromo-1H-indole-3-carbaldehyde, introducing its new discovery. Computed Properties of C9H6BrNO
A mild one-step synthetic method to access privileged heterobiaryl pyrazolo[3,4-b]pyridines from indole-3-carboxaldehyde derivatives and a variety of aminopyrazoles has been developed. This novel method constructs heterobiaryls with the wide scope of substrate generality and excellent regioselectivity via indole ring opening.
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 877-03-2 is helpful to your research. Computed Properties of C9H6BrNO
