Synthesis, characterization and electrochemical properties of novel trinuclear ferrocenyl based organosilane compounds

• 1,1′-Bis(4-chlorobutyl)alkylferrocenes were synthesized.
• A simple method for the preparation of 1,1′-bis(3-butenyl)alkylferrocenes was developed.
• Trinuclear ferrocenyl based organosilane compounds were synthesized.
• The study of electrochemical behavior of these compounds indicates that the electrode processes were diffusion controlled.

Some trinuclear ferrocenyl based organosilane compounds were synthesized by hydrosilylation reaction of [4-(ethylferrocenyl)butyl]dimethylsilane and (4-ferrocenylbutyl)dimethylsilane with bisalkenylferrocene derivatives, in the presence of the Karstedt catalyst at room temperature. In addition a simple method for the preparation of 1,1′-bis(3-butenyl)alkylferrocenes from 1,1′-bis(4-chlorobutyl)alkylferrocenes under mild conditions was developed. 1H and 13C NMR, FT-IR, GC–MS, CHN analysis, atomic absorbtion spectroscopy supported the predicted structure of the products. The electrochemical behavior of synthesized compounds was studied by cyclic voltammetry in CH3CN/0.1 M LiClO4 utilizing a glasse carbon working electrode. The relationship between the peak currents and the square root of the scan rate, showed that the redox process is diffusion limited.

Trinuclear ferrocenyl based organosilane compounds were synthesized by hydrosilylation reaction, in the presence of the Karstedt catalyst. The study of the electrochemical behavior of these compounds indicates that the redox peak currents increase as Fc unit increases in the structure of compounds.Figure optionsDownload as PowerPoint slide
