Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 59-48-3, Name is Indolin-2-one, SMILES is O=C1NC2=C(C=CC=C2)C1, belongs to indolines-derivatives compound. In a document, author is Pugachev, A. D., introduce the new discover, Application In Synthesis of Indolin-2-one.
Replacement of the Hetarene Moiety of Molecule in the Synthesis of Indoline Spiropyran with Cationic Fragment
The paper describes the preparation of a new salt spiropyran of indoline series containing vinyl-3H-indolium fragment in the 8′ position of the 2H-chromene moiety and a chlorine atom in the benzene ring of the indoline fragment. The structure of the reaction product was studied by IR,H-1, and(13)C NMR spectroscopy. The data of X-ray diffraction study indicate that the reaction leads to the partial exchange of the indoline hetarene fragment to provide previously described salt spiropyran containing no chlorine atom in the indoline portion of the molecule.
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 59-48-3 is helpful to your research. Application In Synthesis of Indolin-2-one.
