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, 4062-60-6, name is N1,N2-Di-tert-butylethane-1,2-diamine, introducing its new discovery. Recommanded Product: N1,N2-Di-tert-butylethane-1,2-diamine
Readily prepared cis-beta-(alpha?,alpha?-dimethyl)-4?-methindolylstyrenes undergo acid-catalyzed intramolecular hydroindolation to afford tetrahydrobenzo[cd]indoles. Our experimental and computational investigations suggest that dispersive interactions between the indole and styrene preorganize substrates such that 6-membered ring formation is preferred, apparently via concerted protonation and C-C bond formation. When dispersion is attenuated (by a substituent or heteroatom), regioselectivity erodes and competing oligomerization predominates for cis substrates. Similarly, all trans-configured substrates that we evaluated failed to cyclize efficiently.
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 4062-60-6 is helpful to your research. Recommanded Product: N1,N2-Di-tert-butylethane-1,2-diamine
