Preparation and structure of a stable molecule containing a silicon nitrogen double bond and of its tetrahydrofuran adduct

The pale yellow, solid silaketimine But2N–SiBut3 has been prepared and structurally characterized SiN 1.568(3)Å, Si–N–Si 177.8(2)°; it forms a stable adduct with tetrahydrofuran by complexation of the unsaturated silicon atom.
