摘要/Abstract

摘要：

本文以4-甲基邻苯二甲酸酐为原料, 成功地合成了5,5′-二甲基-2,2′-二茚满-1,1′,3,3′-四酮(2). 通过元素分析、核磁共振、红外光谱及质谱等测试手段, 确定了化合物2的结构与存在形式, 通过ESR测试发现化合物2具有顺磁性.

关键词: 4-甲基苯二甲酸酐; 异构化; 氢键

Abstract:

Based on the synthesis of 2,2′-bisindan-1,1′,3,3′-tetrone(1), 5,5′-dimethyl-2,2′-bisindan-1,1′,3,3′-tetrone(2) was obtained. This paper described the synthetic process and confirmed the characteristic of compound 2 by elemental analysis, ¹H NMR, FTIR and MS, then discussed a possible existing form. Compound 2 maily existed as en-ol form and had H-bonds in the molecule. At the same time, the ESR value of compound 2 was given as g=2.0042, could form stable radical.

Key words: 4-Methylphthalic anhydride; Isomerization; Hydrogen bond
