Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. , SDS of cas: 86-99-7, 86-99-7, Name is 7-Chloroquinolin-4-ol, molecular formula is C9H6ClNO, belongs to quinoxaline compound.

Synthesis of polyfluorinated 4-hydroxyquinolin-2(1H)-ones based on the cyclization of 2-alkynylanilines with carbon dioxide
Convenient and efficient synthesis of polyfluorinated 4-hydroxyquinolin-2(1H)-ones from the corresponding oalkynylaniline derivatives and CO2 (1 atm), mediated by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and AgNO3 in acetonitrile was performed. This synthetic methodology may be used to prepare fluorinated heterocycles containing peripheral alkynyl and amino groups but is not suitable for silylethynyl derivatives that give indoles as the main products. The reaction takes place under mild conditions (60 degrees C) and involves readily available starting materials that include cheap and renewable carbon dioxide.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 86-99-7. SDS of cas: 86-99-7.
