Ferrocenyl β-diketones containing benzene ring have been synthesized and characterized. The content of enol isomer is almost 100% in β-diketone containing nitro group, and decreases to 84% in that containing methoxy group in CDCl3 from 1H NMR. When they were converted to the Cu(II) or Ni(II) complexes, the stretching bands of C=O and C=C in enol isomers shifted 57～69 and 10～27 cm-1 to low wave number, respectively. The absorption bands below 300 nm assignabling to Fe(d)-π* and π-π* electronic transitions of the aromatic rings in UV-vis absorption spectra shifted bathochromically 5～17 nm. The thermogravimetry-differential scanning calorimetry (TG-DSC) measurements confirmed that not only the sublimation for ammonium perchlorate (AP) on the high-temperature decomposition stage was inhabited but also the obvious catalytic effect on the decomposition of AP was found after adding these ferrocenyl β-diketones or their Cu or Ni complexes to AP, and the Cu complexes had the most significant effect. The Cu complex containing methoxy group decreased the decomposition temperature of AP by 87 ℃. So the Cu complexes are more effective catalysts than ferrocenyl β-diketone ligands and the Ni complexes.
