无水碳酸钾存在下6-氯-5, 12-萘并萘醌与4-羟基偶氮苯在干燥DMF中反应的主要产物在某些反应条件下不是6[4-(苯基偶氮基)苯氧基]-5, 12-萘并萘醌(1)。该未知反应产物2经核磁共振方法研究证实是6-(N, N-二甲氨基)5, 12-萘并萘醌。本文对化合物2的1H-和13C化学位移、偶合信息和结构作了详细归属, 并推测其反应进程, 实验结果表明, 化合物2是由化合物1与溶剂DMF反应生成。

The reaction product of 6-chloro-5, 12-naphthacenequinone with 4-hydroxyazobenzene in the dried DMF in the presence of anhydrous potassium carbonate was not the anticipated 6-[4-(phenylazo) phenoxy]-5, 12-naphthacenquinone (1) under certain reaction conditions. This unknown product 2 was proved by NMR studies to be 6-(N, N-dimethylamino)-5, 12-naphathacenequinone. Its 1H and 13C NMR chemical shifts, coupling information and structure were assigned in detail. The compound 2 may be formed by the reaction of 1 and the solvent DMF.
