The reaction conditions for the preparation of 7H,8H-1,3-dimethyl-2,4,6,9-tetraoxopyrimidino[4,5-b][1,4]-diazocine (9), 1,3-dimethy 1–2,4,6,11-tetraoxobenzo[f]pyrimidino[4,5-b][1,4]diazocine (10), 7H,8H-1,3-dimethyl-2,4,6,10-tetraoxopyrimidino[4,5-b][1,4]diazonine (16), and 7H,8H-6,9-dioxopyridino[2,3-b][1,4]diazocine (19) were determined. The mechanism of the formation of these compounds was established
制备7 H,8 H -1,3-二甲基-2,4,6,9-四氧嘧啶并[4,5- b ] [1,4]-重氮(9),1,3-的反应条件二甲基1–2,4,6,11-四氧苯并[ f ]嘧啶基[4,5- b ] [1,4]重氮(10),7 H,8 H -1,3-二甲基-2,4,6 ,10-四氧嘧啶并[4,5- b ] [1,4]重氮(16)和7 H,8 H -6,9-二氧吡啶并[2,3- b ] [1,4]重氮(19)确定。建立了这些化合物的形成机理。发现这些反应的范围一般是由2,3-二氨基-N-杂环形成8和9个环。
