5-, 6-, 7- and 8-trimethylsilylquinolines and their methiodides as well as some 2-silyl-alkylquinolines were obtained by lithium synthesis in order to elucidate intramolecular donor-acceptor interactions between nitrogen and silicon atoms. 1H, 13C, 14N, 15N and 29Si NMR spectra of the compounds were studied and quantum-chemical calculation of charges on individual atoms in the unsubstituted quinoline
