Lithium-Iminofluorsilan und Natriumfluorsilylamid – ein Vergleich / Lithium-Iminofluorosilane and Sodium-Fluorosilylamide – a Comparison

Abstract

The metalation of 2,4,6-tri-tert-butylamino-tert-butylfluoromethylsilane (1) with butyllithium leads to the formation of the LiF adduct of the iminosilane 2. In 2 the silicon atom is pentavalent and four-coordinated. The corresponding sodium compound is the fluorosilylamide 3. The nitrogen has a planar environment in 3.
