The synthesized ferrocene since the 1950s to date, the majority of chemical workers of ferrocene and derivatives extensive and in-depth research. Studies have shown that ferrocene and its derivatives in a wide range of applications in areas such as catalysis, materials, bio-pharmaceutical, chemical analysis, electrochemical. Further synthesis of new ferrocene derivatives, and in-depth study of the nature and application of the compound, has been one of the focuses of the research at home and abroad. This thesis, do the following: In a nitrogen atmosphere, 1,1 '- the ferrocene double formic hydrazide and 3,4 - hydroxybenzaldehyde, vanillin, 4 - hydroxybenzaldehyde, 3 - hydroxy formaldehyde, 4 - methoxybenzaldehyde and salicylaldehyde role of, synthesis of to six novel ferrocene bis formyloxy hydrazone compounds FCL1 FcL6: Fc (CONHN = CH-R) 2 {R were above the six aldehyde}; nitrogen atmosphere, ferrocene single formyl hydrazine and 2,4 - dihydroxyphenyl formaldehyde, 2 - thienyl formaldehyde and 4,5 - diazafluorene -9 - ketone role, synthesized three novel the to the ferrocene single formylation hydrazones on compound FcL7-FcL9: Fc (CONHN = CH-R) {R, respectively, for the above-described three aldehyde}; under a nitrogen atmosphere, the dicyclopentadienyl iron monoacyl propanehydrazide, respectively, and 2,4 - hydroxybenzaldehyde, 3 - hydroxybenzaldehyde role, synthesis of two new ferrocene acyl propionyl hydrazone compounds FcL10 ~ FcL11: Fc (COCH2CONHN = CH-R) {R, respectively, for the above two aldehydes} and the use of infrared spectroscopy, elemental analysis, 1H NMR spectroscopy analysis methods were used to characterize the FcL1-FcLll. Meanwhile, the compound FcL7 FcL8 two single, the molecular structure of the crystal was measured by X-ray diffraction, and Gaussian software on molecular orbital energy level of the two crystals, the energy calculation and analysis. Studied by cyclic voltammetry, electrochemical properties of the ferrocene acylhydrazone and determination of kinetic parameters. The study showed that: 11 ferrocene acylhydrazone redox reaction occurs at the electrode surface, and the reaction on the electrode are subject to diffusion control. Different ferrocene single carboxamido substituted derivative occur at the electrodes is reversible redox chemical reactions, while the bis-hydrazones occurred is not reversible or quasi-reversible reaction. Further, the compound FcL7 divalent lead ions obvious electrochemical response, the use of this nature can be used in solution Pb2 identification. The UV spectrum of the compound shows that ferrocene acylhydrazone similar absorption in the range of 200-400nm, the compound FcL8 respect to other compounds an absorption peak.
