摘要

Abstract α-diamines, such as ethylendiamine and o-phenylendiamine, add to 3, 4-aryl- disubstituted 1, 2, 5-thiadiazole 1, 1-dioxides to give dihydropyrazines or quinoxalines, respectively and sulfamide. The new compound acenaphtho [5, 6-b]-2, 3-dihydropyrazine was synthesized and characterized. The addition of ethylendiamine to 3, 4-diphenyl-1, 2, 5- thiadiazoline 1, 1-dioxide gives 3, 4-disubstituted thiadiazolidine 1, 1-dioxide, ...
