Though the chlorination of an N,N′-annelated phenanthrolinedione, 3,6,7,9-tetrahydro-5H-[1,4]diazepino[1,2,3,4-lmn][1,10]phenanthroline-3,9-dione, gave 2,9-dichloro-1,10-phenanthroline, another dione, 3,5,6,8-tetrahydropyrazino[1,2,3,4-lmn][1,10]phenanthroline-3,8-dione, did not. It demonstrated a simultanous introduction of two chlorine substituents to non-substituted 1,10-phenanthroline via only the former intermediate.
虽然N,N′-茚并菲咯啉二酮(3,6,7,9-四氢-5H-[1,4]二氮杂卓[1,2,3,4-lmn][1,10]菲咯啉-3,9-二酮)的氯化反应产生了2,9-二氯-1,10-菲咯啉,但另一种二酮(3,5,6,8-四氢吡嗪[1,2,3,4-lmn][1,10]菲咯啉-3,8-二酮)却没有。它表明,仅通过前一种中间体,即可同时向非取代的1,10-菲咯啉引入两个氯取代基。
