Pyrolysis of 4,4-diaryl-1,4-dihydro-2H-3,1-benzoxazin-2-ones at 230–240 °C gives 9-arylacridines and (2-aminophenyl)diarylmethanes. Their formation correlates well with the mass fragmentation of the respective parent compounds.
4,4-二芳基-1,4-二氢-2H-3,1-苯并恶嗪-2-酮在 230–240 °C 下热解得到 9-芳基
吖啶和(2-
氨基苯基)二芳基
甲烷。它们的形成与各自母体化合物的质量碎裂密切相关。
