Abstract
Abstract Dimethylamino-bis[tris(trimethylsilyl)silyl]methane (5) is prepared by the reaction of tris(trimethylsilyl)silyllithium (1) with chloromethylene-dimethyliminium chloride. The proposed mechanism of the formation of 5, leading to the fixation of two bulky hypersilyl groups at one comparatively small carbon atom, is discussed. The structure of 5, elucidated by an X-ray crystal structure analysis, is characterized by tremendous distortions of the molecular skeleton due to the spatial demand of the two extended hemispherical (Me3Si)3Si groups, causing for example a central Si–C–Si angle of 132.6°.
