摘要：

Based on the synthesis of 2,2'-bisindan-1, 1',3,3'-tetrone( 1), 5,5'-dimethy1-2,2'-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, (1)H 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.
