| Abstract: | Halogeno- and Aminofunctional Tris(trimethylsilyl)silyl-silanes Lithium-tris(trimethylsilyl)silane 1 reacts with halogenosilanes to give thermally stable compounds of the type  ( 2 – 11 ). The substitution of the bulky (trimethylsilyl)amino group occurs in reactions of 1 with aminofluorosilanes —  ( 12 – 14 ). In excess 1 reacts with 2–14 under formation of (Me3Si)4Si. The substitution compounds 15–17 are obtained in the reaction of 3 and 9 with lithium salts of primary amines. The 1,3-diaza-2,4-disilacyclobutan 18 is formed by HF-elimination of 15 . |
