    摘要:
    SiCln(NR2)4-n (n = 1, 2, 3, 4) 中 Si–Cl 键的氨解反应已被用于合成二元氨基、氯氨基或混合氨基衍生物,这取决于硅衍生物和胺的性质。反应动力学在一些代表性案例中进行了研究,即 SiCl4 + NHiPr2、SiCl(NMe2)3 + NH2iPr、SiCl2(NEt2)2 + NH2iPr,结果表明速率法则对硅化合物是一阶反应,并且不依赖于胺的浓度。此外,已确定 SiCl2(NEt2)2 与 NH2iPr 的反应的活化参数。SiCl4 和 SiCln(NR2)4-n 之间的配体交换反应生成多种氯氨基衍生物,其组成严格由反应物的摩尔比决定。对于 n = 3(R = Me)和 n = 2(R = Et),研究了 SiCl4 与 SiCln(NR2)4-n 之间的反应动力学。此外,在后者的情况下已确定平衡和活化参数。

    reaction between tetrakis(ethylamino)silane, Si(NHEt)4 (1) and trialkylaluminium compounds AlR3 [R = Me (2), R = Et (3)] results in partial deprotonation of 1 and subsequent formation of a new dimeric alumosilazane in high yield. Single-crystal X-ray analyses reveal the structure of two new four-membered ring compounds [RAl(μ-NHEt)(μ-NEt)2Si(NHEt)]2 [R = Me (4), R = Et (5)]. They are isostructural and crystallize
