Bis(oligosilanyl)chalcogenides [(Me3Si)xMe3−xSi]2E, alkalimetal oligosilanylchalcogenolates (Me3Si)xMe3−xSiEMI and oligosilanylchalcogenols (Me3Si)xMe3−xSiEH (E=S, Se, Te): Syntheses and NMR study

Bis(oligosilanyl)chalcogenides [(Me3Si)xMe3−xSi]2E, alkalimetal oligosilanylchalcogenolates (Me3Si)xMe3−xSiEMI and oligosilanylchalcogenols (Me3Si)xMe3−xSiEH (x=1–3; E=S, Se, Te) were synthesized and characterized by 1H-, 13C-, 29Si-, 77Se- and 125Te-NMR spectroscopy. Trends of NMR parameters (chemical shifts, coupling constants) are discussed.
