by two by-products, a six-membered Si(SiO)2NH-ring (10) and a 1,3-diamino-1,3-disiloxane (11). The treatment of 6 with n-C4H9Li followed by LiF-elimination results in an eight-membered (SiOSiN)2-ring (13), the analogous reaction of 7 and 8 leads to the formation of four-membered (SiOSiN)-rings (14, 15). The results of the crystal structure determinations of 2, 3, 9 the lithium salt of 8 (12) and quantum
氨基二叔丁基硅烷醇(1)结晶为二聚体。它形成钠和钾aminosilanolates(2,3在固体状态),其结晶为六方柱。在碱金属-氨基硅烷醇化物与卤代硅烷的反应中,获得1-氨基-1,3-二硅氧烷(Me 3 C)2 Si(NH 2)OSiRR'R“;(4:R = R′= CMe 3,R″ = H;5:R″ = Cl;6:R = Me,R′= CMe 3,R″ = F;7:R = R′= NMeSiMe 3, R '' = F; 8:R = R'= NCHMe 2 SiMe 3,R” = F;9:R = R′= N(CHMe 2)2,R″ = F)。5的形成伴随有两种副产物,六元Si(SiO)2 NH-环(10)和1,3-二氨基-1,3-二硅氧烷(11)。用n -C 4 H 9 Li处理6之后再进行LiF消除,得到八元(SiOSiN)2环(13),7和8的类似反应导致形成四元(SiOSiN)
