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

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. H-1 and C-13 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. (C) 2014 Elsevier B.V. All rights reserved.
