1,2-Bis(trimethylsilyl)-1,2-diphenylethane and its homologues were syn
thesized and the studies on their electrochemical behavior revealed th
at there is definite interaction between the sigma,pi-interaction syst
em (the C-Si bonds and the benzene rings) and the sigma,sigma-interact
ion system (the neighboring C-Si bonds) which causes significant decre
ase of the oxidation potentials.
