Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 619-67-0, Name is 4-Hydrazinylbenzoic acid, SMILES is O=C(O)C1=CC=C(NN)C=C1, belongs to phthalazine compound. In a document, author is Yuan, Chunhao, introduce the new discover, Safety of 4-Hydrazinylbenzoic acid.
The Cu(I)-catalyzed highly enantioselective [3 + 3] cycloaddition between two different 1,3-dipoles, phthalazinium dicyanomethanides and iminoester-derived azomethine ylides, has been achieved under mild reaction conditions, providing novel chiral heterocyclic compounds, 2,3,4,11b-tetrahydro-1H-pyrazino[2,1-a]phthalazine derivatives, in high yields with excellent diastereo- and enantioselectivies (up to 99% yield, 99% ee, >20:1 dr).
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 619-67-0 is helpful to your research. Safety of 4-Hydrazinylbenzoic acid.
