On April 30, 1986, Houminer, Y.; Southwick, E. W.; Williams, D. L. published an article.Application In Synthesis of 5,6,7,8-Tetrahydroquinoxaline The title of the article was Preparation of monoacylpyrazines. And the article contained the following:
Homolytic acylation of pyrazine and alkylpyrazines by aldehydes, as a source of an acyl radical, gives mainly monoacylation products. The reactions proceed in reasonable yields and provide a new route to pyrazine ketones. Thus, stirring pyrazine with EtCHO in water in the presence of H2SO4, t-BuOOH, and FeSO4 gave 29% pyrazine I. The experimental process involved the reaction of 5,6,7,8-Tetrahydroquinoxaline(cas: 34413-35-9).Application In Synthesis of 5,6,7,8-Tetrahydroquinoxaline
