Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 90-59-5, Name is 3,5-Dibromo-2-hydroxybenzaldehyde, SMILES is O=CC1=CC(Br)=CC(Br)=C1O, belongs to indole-building-block compound. In a document, author is Liddon, John T. R., introduce the new discover, Product Details of 90-59-5.
A combined synthetic and computational (DFT) study has been performed to account for the divergent reactivity of indole-tethered ynones when treated with Ag(I) and Au(I) catalysts. The two catalyst systems deliver spirocyclic indolenines and carbazoles, respectively, from the same precursors, with the reaction outcomes believed to be a result of differences in the rates of a key protodemetalation step. A ring-opening/ ring-closing isomerisation process is proposed to enable the interconversion of spirocyclic and C-2 annulated indole intermediates, in contrast to the 1,2-migration mechanism tentatively proposed in previous studies.
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 90-59-5 is helpful to your research. Product Details of 90-59-5.
