| 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. |
