摘要：
Lithium derivatives of silylhydroxylamines are used for more than thirty years. Now we are able to present the first crystal structures. Lithium is bonded side on and end on in these silylhydroxylamides. Depending on the reaction conditions and the bulkiness of the substituents dimeric, trimeric, and tetrameric oligomers are found. Fluoro-functional bis(silyl)hydroxylamines are excellent precursors for rings. By-products of the syntheses of bis(silyl)hydroxylamines are N, bis(silyl)ethylendiamines, which are easily cyclized forming l, 2-diaza-2-silacyclopentanes. Reactions and X-ray analyses are discussed.
