Oxidation of 1,3-diphenyl-4,7-phenanthroline with potassium permanganate in alkaline medium results in transformation of the 4,7-phenanthroline ring system into 1,8-diaazafluorenone. Oxidation of 12-aryl-and 12-aryl-9,9-dimethyl-8,9,10,12-tetrahydro-7H-benzo[b][4,7]phenanthrolin-11-ones (condensation products of 6-arylmethylene-aminoquinolines with 1,3-cyclohexanedione and dimedone) with sodium nitrite in acetic acid leads to 12-aryl-9,10-dihydro-8H-benzo[b][4,7]phenanthrolin-11-ones. 13-Aryl-7,13-dihydro-12H-indeno-[2,1-b][4,7]phenanthrolin-12-ones obtained by reaction of 6-arylmethyleneaminoquinolines with 1,3-indandione are oxidized to 13-aryl-12H-indeno[2,1-b][4,7]phenanthrolin-12-ones on heating in nitrobenzene.
在碱性介质中用高锰酸钾氧化 1,3-二苯基-4,7-菲罗啉,会使 4,7- 菲罗啉环系统转化为 1,8-二氮芴酮。在醋酸中用亚硝酸钠氧化 12-芳基和 12-芳基-9,9-二甲基-8,9,10,12-四氢-7H-苯并[b][4,7]菲罗啉-11-酮(6-芳基亚甲基氨基喹啉与 1,3-环己二酮和二咪酮的缩合产物),可生成 12-芳基-9,10-二氢-8H-苯并[b][4,7]菲罗啉-11-酮。由 6-芳基亚甲基氨基喹啉与 1,3-茚二酮反应得到的 13-芳基-7,13-二氢-12H-茚并[2,1-b][4,7]菲罗啉-12-酮在硝基苯中加热后氧化成 13-芳基-12H-茚并[2,1-b][4,7]菲罗啉-12-酮。
