Acyclic Amido‐Containing Silanechalcogenones

Abstract

Abstract Reactions of the amidinate‐stabilized silicon(II) bis(trimethylsilyl)amide [LSiN(SiMe 3 ) 2 ], {L = PhC(N t Bu) 2 , 1 } with a stiochiometric amount of elemental sulfur, selenium and tellurium afforded the first stable silanechalcogenones comprising an acyclic amido substituent [L{N(SiMe 3 ) 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.
