 Title    Reaktionen von Lithio-aminofluorsilanen mit Halogensilanen und Trimethylzinnchlorid Reactions of Lithio-aminofluorosilanes with Halogensilanes and Trimethyltinchloride  
 Abstract    Fluorosilanes react with lithium amides and organolithium compounds to give amino-fluorosilanes. (Lithioamino)fluorosilanes are formed by the reaction of aminofluoro-silanes with butyllithium depending on the steric influence and molecular stabilization of the ligands. These lithium salts react with halogensilanes and trimethyltin chloride with substitution. By LiF elimination the lithio-aminofluorosilane C6H5-SiF-NLiC(CH3)3-N(p-C6H4CH3Si(CH3)3) cyclisizes through a (2-j-2)cycloaddition and SiC-H-cleavage.
