中文摘要	six beta-diketone compounds, 1,3-bis(4-nitrophenyl)-1,3-propanedione (1), 1-(4-nitrophenyl)-3-(3-nitrophenyl)-1,3-propanedione(2), 1,3-bis(3-nitrophenyl)-1,3-propanedione(3) 1,3-bis(4-amimophenyl)-1,3-propanedione(4), 1-(4-amimophenyl)-3-( 3-amimophenyl)-1,3-propanedione(5) and 1,3-bis (3-amimophenyl)-1,3-propanedione(6) were synthesized, their structures were characterized by ir, uv-vis, fluorescence and nmr spectroscopy, the percentage of keto tautomer, enol-keto equilibrium constant and enol tautomer ratio of them were also determined, the percentage of keto tautomer is increased in the order from compound 1 to 3 and decreased in the order from compound 4 to 6, which show the effect of substituent on the tautomer. the results of enol tautomer ratio of compounds 2 and 5 indicated that b-form of enol is slightly more favorable than its a-form.
