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.

Some new branched polysilyl ethers with a ferrocene core were synthesized through treatment of 1,1'-bis[tris(dimethylsilyl)methyl] alkylferrocenes with various alcohols by Karstedt catalyst. Bis(chloroalkyl) ferrocenes are synthesized by acylation of ferrocene with 3-chloropropanoyl chloride and 4-chlorobutanoyl chloride. The obtained 1,1'-bis(3-chloropropanoyl) ferrocene and 1,1'-bis(4-chlorobutanoyl) ferrocene underwent a reduction and chlorides were replaced by bromides, and then they were treated with (Me3Si)(3)CLi and (HMe2Si)(3)CLi give silane compounds 6a-b and 7a-b.
