Treatment 2‐arylmethyleneaminoisoindole‐1,3‐diones 1a–c with arenes in the presence of AlCl3‐DMF complex as a catalyst afforded the novel compounds, 2‐((arylidenehydrazono)(aryl)‐methyl)benzophenones 3a–n in satisfactory yields. The structure of the obtained products 3a–n was confirmed by the use of IR, 1H‐NMR, 13C‐NMR, mass spectra, and elemental analyses.
在AlCl 3 -DMF络合物作为催化剂存在下,用芳烃处理2-芳基亚甲基氨基异吲哚-1,3-二酮1a - c,得到令人满意的新型化合物2-(((芳基叠氮基)(芳基)-甲基)二苯甲酮3a - n。产量。所得产物3a - n的结构通过红外光谱,1 H-NMR,13 C-NMR,质谱和元素分析得到证实。
