Abstract: Non-homogenous condensation of alkylferrocenes with acetone has been carried out in the presence of methyl alcohol and concentrated sulfurric acid. Two series of compounds, 2,2-bis(monoalkylferrocenyl)propanes and 2,2-bis(dialkylferrocenyl)propanes were isolated by column chromatography. It was found the optimal conditions were n(alkylferrocene):n(acetone):n(concentrated sulfuric acid):n(methyl (alcohol)=)1:0.55:2:6.7, reaction time 4~6 h, and reaction temperature 80~90℃. The structures of these compounds were characterized by elemental analysis, IR, and ¹H NMR. The electrochemical properties of these compounds were investigated by cyclic voltammetry. The results indicated that the burning-rate catalytic efficiency of the title compounds showed a slow decrease with the increase of the alkyl chain length, and for the alkyl group with same carbon number, the more alkyl groups the stronger the electron repulsion and reducibility, and hense the higher the burning-rate catalytic activity. The effect of the structures, electrochemical properties, and catalytic activity on the burning-rate were also discussed.
