phosgene, thiophosgene and thionylchloride to give the corresponding bisfused oxadiazolo- and oxathiadiazoloquinoxalines 2, 4, 5 along with the unexpected furazano-derivative 3, while monoamidoximes 9, 13 by treatment with ethyl chloroformate affords the oxadiazoloquinoxaline and the oxadiazolobenzothiazine derivatives 14, 15 along with the dicarboxylated product 16.
双-偕胺肟1种发生反应与光气,硫光气和亚硫酰氯,得到相应的bisfused oxadiazolo-和oxathiadiazoloquinoxalines 2,4,5一起意想不到furazano衍生物3,而monoamidoximes 9,13通过用氯甲酸乙酯处理,得到oxadiazoloquinoxaline和oxadiazolobenzothiazine衍生物14、15以及二羧酸化产物16。
