The Permethylcyclosilanes (Me2Si)5 through (Me2Si)35

The cyclic permethylpolysilanes (Me2Si)n, where n = 5-35, are all formed when dimethyldichlorosilane (Me2SiCl2) is added slowly to sodium-potassium (Na/K) alloy in tetrahydrofuran (THF).NMR, UV, and vibrational spectra are reported for compounds n = 5-19.The 13C NMR and 1H NMR spectra are explained in terms of methyl-methyl group interactions.Raman and IR spectra are assigned and partially explained on the basis of a standing wave model.
