The hydrazidosilanes Ph2Si(NHNMe2)2 (1), Me2Si(NHNMe2)2 (2), PhSi(NHNMe2)3 (3), MeSi(NHNMe2)3 (4), PhClSi(NHNMe2)2 (5), MeClSi(NHNMe2)2 (6), Me2ClSi(NHNMe2) (7), MeClHSi(NHNMe2) (8), MeHSi(NHNMe2)2 (9), Me2HSi(NHNMe2) (10), Me2NN[HSi(NHNMe2)2]2 (11) and Si(NHNMe2)4 (12) have been prepared by the reaction of the corresponding chlorosilanes with N,N-dimethylhydrazine. Some of the compounds containing SiâCl and NâH functions simultaneously (6, 7, 8) are very reactive and tend to polymerise and could only be characterised by spectroscopic methods (1H, 13C, 29Si NMR, IR, MS). All other compounds could additionally be characterised by elemental analyses. The structures of 1, 2, 5, 9, 11 and 12 in the solid state were determined by X-ray diffraction. These include the first structural determinations of compounds containing SiHâNHâN (9, 11) and SiClâNHâN (5) units.
叠氮硅烷Ph2Si(NHNMe2)2(1)、Me2Si(NHNMe2)2(2)、PhSi(NHNMe2)3(3)、MeSi(NHNMe2)3(4)、PhClSi(NHNMe2)2(5)、MeClSi(NHNMe2)2(6)、Me2ClSi(NHNMe2)(7)、MeClHSi(NHNMe2)(8)、MeHSi(NHNMe2)2(9)、Me2HSi(NHNMe2)(10)、Me2NN[HSi(NHNMe2)2]2(11)和Si(NHNMe2)4(12)通过相应的氯硅烷与N,N-二甲基肼反应制备得到。一些同时含有Si-Cl和N-H官能团的化合物(6,7,8)反应性很高,倾向于聚合,只能通过光谱学方法(1H、13C、29Si NMR、IR、MS)进行表征。所有其他化合物还可以通过元素分析进行表征。1、2、5、9、11和12的固态结构通过X射线衍射确定。这些包括首次含有SiH-NH-N(9,11)和SiCl-NH-N(5)单元的化合物的结构确定。
