In 1997,Australian Journal of Chemistry included an article by Deady, Leslie W.; Kaye, Anthony J.. Electric Literature of C15H10N2O2. The article was titled 《Fused tetracyclic quinoxalines from reactions of o-phenylenediamines in polyphosphoric acid》. The information in the text is summarized as follows:
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, e.g., I. Isomeric products are formed from these unsym. diamines, and methods of assigning particular structures are described. The results came from multiple reactions, including the reaction of 3-Phenylquinoxaline-5-carboxylic acid(cas: 162135-93-5Electric Literature of C15H10N2O2)
3-Phenylquinoxaline-5-carboxylic acid(cas: 162135-93-5) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with TCDD being one of the most notorious.Electric Literature of C15H10N2O2
