  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

  Ethylenediamine reacts with chlorosilanes to give N,N′-bis(silyl)ethylenediamines [(H₂CNHSiRR′R″)₂, 3: R, R′ = Me; R″ = CMe₃; 4: R = H; R′, R″= CMe₃; 5: R,R′ = CMe₃, R″ = OH]. In the reaction of N,N,N′-tris(trimethylsilyl)ethylenediamine with SiF₄ the difluoro-bis(1.1.4- tris(trimethylsilyl)ethylenediamino)silane (6) is obtained. The 1.3-diaza-2-silacyclopentanes R₂Si[N(SiMe₂R′)CH₂]₂, 7 - 10 (7: R = Cl, R′= Ph; 8: R = Cl, R′ = CMe₃; 9: R = H, Cl, R′ = CMe₃; 10: R = Br, R′ = CMe₃) are isolated from the reactions of the corresponding bis(silyl)ethylenediamines and halosilanes in Et₂O with NEt₃ as HHal acceptor. Dilithium derivatives of N,N′-bis(silyl)ethylenediamines react with fluorosilanes with formation of the 1.3-diaza-2-silacyclopentanes, R₂Si[N(SiMe₂R′)CH₂]₂ (11 - 13) (11: R = F,R′ =Me; 12: R = F, R′ = CMe₃; 13: R = CHMe₂, R′ = Me). N-Fluoro-di(tert-butyl)silyl-N,N′-bis(trimethylsilyl)- ethylenediamine (14) is formed in the reaction of lithiated bis(trimethylsilyl)ethylenediamine with F₂Si(CMe₃)₂. 8 reacts in amolar ratio 1:2 withNaNH₂ or NaOMe with formation of 15 and 16, respectively · R₂Si[N(SiMe₂CMe₃)CH₂]₂, 15: R = NH₂; 16: R = OMe]. 1.3-Bis(tert-butyldimethylsilyl)- 2-tert-butyldimethylsiloxy-2-fluoro-1.3-diaza-2-silacyclopentane is the product of the reaction of 12 with LiOSiMe₂CMe₃. The crystal structures of 6 and 13 have been determined.
