Reference of 162135-93-5, 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.In a document type is Article, and a compound is mentioned, 162135-93-5, 3-Phenylquinoxaline-5-carboxylic acid, introducing its new discovery.
Fused Tetracyclic quinoxalines from reactions of o-phenylenediamines in polyphosphoric acid
The condensation of 2,3-diaminobenzoic acid and the 5-chloro derivative with o-hydroxyphenylglyoxylic acid, isatin and benzothiophen-2,3-dione in polyphosphoric acid leads to the appropriate tetracycles. Isomeric products are formed from these unsymmetrical diamines, and methods of assigning particular structures are described.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Reference of 162135-93-5. In my other articles, you can also check out more blogs about 162135-93-5
