Abstract

Reactions of the amidinate-stabilized silicon(II) bis(trimethylsilyl)amide [LSiN(SiMe₃)₂], {L = PhC(NtBu)₂, 1} with a stiochiometric amount of elemental sulfur, selenium and tellurium afforded the first stable silanechalcogenones comprising an acyclic amido substituent [L{N(SiMe₃)₂}Si=E] {E = S (2), Se (3) or Te (4)}. All compounds were characterized by X-ray crystallography and multinuclear NMR spectroscopy. The results illustrate that these compounds possess some silicon-chalcogen double bond character. Reactions of the amidinate-stabilized silicon(II) bis(trimethylsilyl)amide [LSiN(SiMe₃)₂], {L = PhC(NtBu)₂, 1} with a stiochiometric amount of elemental sulfur, selenium and tellurium afforded the first stable silanechalcogenones comprising an acyclic amido substituent, [L{N(SiMe₃)₂}Si=E] {E = S (2), Se (3) or Te (4)}.
