Reactions of bis[bis(trimethylsilyl)amido] zinc with amides of sulfonimidic acids. Crystal structure and NMR studies of bischelate zinc complex

Reactions of bis[bis(trimethylsilyl)amido] zinc with amides of sulfonimidic acids are leading to the corresponding bischelate complexes 1–3. Compounds 1–3 were characterized by means of NMR spectroscopy and elemental analysis. The X-ray analysis of [p-MeC6H4S(O)(Nt-Bu)2]2Zn (3) demonstrates a tetrahedral environment of the Zn atom in the solid state and dynamic 1H NMR studies showed interconvention between two conformers in solution at high temperatures.
