Abstract

Three types of silicon podands, Me2Si(OR)2, EtSi(OR)3 and PhSi(OR)3, where R is a polyoxaethylene chain with different numbers of oxygen atoms (two, three or four), were obtained and studied by 1H, 13C and 29Si NMR methods. NMR spectra of 1H, 7Li, 13C, 23Na and 29Si nuclei were also used for the study of lithium, sodium and rubidium complexes with the silicon podands. Theoretical calculations were performed using the PM3 hamiltonian. The heats of reactions between the compounds obtained and SbCl5 were determined.
