Das chlorsilylsubstituierte Silanimin tBu2SiNSiCltBu2
摘要:
In the thermolysis of the silaterazolines sitatetrazoline (Bu2Si)-Bu-t=N-SiCl'Bu-2 center dot (Bu3SiN3)-Bu-t the silanimine (Bu2Si)-Bu-t=N-(SiClBu2)-Bu-t and the silyl azide (Bu3SiN3)-Bu-t are formed quantitatively. The silanimme (Bu2Si)-Bu-t=N-(SiClBu2)-Bu-t has been trapped with Et3NHF, Me3NHCl, water, 1-butene, 2,3-dimethyl-1,3-butadiene, isobutene, methylvinyl ether, and (Bu2SiCIN3)-Bu-t. The structure of the disiloxane (Bu-t(2)-SiCl-NH-(SiBu2)-Bu-t)(2)O kand of the bis(di-tert-butylchlorsilyl)-substituted silatetrazoline (Bu2Si)-Bu-t=N-SiCl(t)Bu(2)center dot(t)Bu(2)SiCIN(3) has been determined by X-ray structure analysis.

produce EtN(Me)CH2 SiMe 2N(H)SitBu 3 and EtN(Me)CH-[Me 2 SiN(H)SitBu 3 ] 2 , and EtN(Me)CH2 SitBu 2N(H)SiCltBu 2 , respectively. In contrast, the thermolysis of Me 2Si=NSitBu 3 . NMe 2 Et in vacuo gives the silanimine dimer (Me 2 SiNSitBu 3 ) 2 (monoclinic, P2 1 /n) in 80 % yield. The benzophenone imine Ph 2 C=NSitBu 3 (triclinic, P1) was obtained from the Wittig-like reaction of Me 2Si=N-SitBu 3
与 tBu 2 SiN(Li)SiXtBu 2 (X = Cl, tBu) 相比,甲硅烷基酰胺 Me 2 SiClN(Li)SitBu 3 对 LiCl 消除不稳定,这意味着硅胺给体加合物 Me 2 Si=NSitBu 3 · NMe 2 Et 可以通过 Me 2 SiClN(H)SitBu 3 与 nBuLi 在 NMe 2 Et 存在下的反应以高产率合成。硅胺加合物tBu 2 Si=NSiCltBu 2 ·NMe 2 Et,在不饱和Si 中心具有庞大的tBu 取代基,可通过用NMe 2 Et 处理无供体的硅烷胺tBu 2 Si=NSiCltBu 2 来获得。硅烷胺加合物 Me 2 Si=NSitBu 3 ·NMe 2 Et(单斜晶系,P2 1 /n)的 X 射线质量晶体从戊烷在 -25 °C 下生长。在作为溶剂的 NMe 2 Et 中,加合物 Me 2 Si=NSitBu 3 ·NMe
