Ahmad, Yusuf published the artcileQuinoxaline derivatives. XI. Reaction of quinoxaline 1,4-dioxide and some of its derivatives with acetyl chloride, Formula: C9H6Cl2N2, the main research area is quinoxaline dioxide reaction; acetyl chloride reaction; chloroquinoxaline dioxide.
Quinoxaline 1,4-dioxide with AcCl gives 6-chloroquinoxaline 1-oxide (I). On heating, and progressively increasing the time of reaction, the yield of I increases, and 3-chloroquinoxaline 1-oxide, and 6.7-dichloroquinoxaline appear as addnl. products. 7-Ethoxy-, 7-methoxy-, 7-methylquinoxaline 1,4-dioxides show a similar behavior, giving corresponding 6-chloro, and 3-chloro derivatives as main products. Further increase in the reaction time results in the formation of 2,6-dichloro and 2,3-dichloro compounds as addnl. products. However, none of the 2-chloro 4-oxide derivatives were isolated. The mechanisms for these transformations were proposed and discussed.
Journal of Organic Chemistry published new progress about Chlorination. 39267-05-5 belongs to class quinoxaline, name is 2,3-Dichloro-6-methylquinoxaline, and the molecular formula is C9H6Cl2N2, Formula: C9H6Cl2N2.
