Abstract
The reaction of SiCl4 with Na[SitBu3] in thf at −78 °C yielded tBu3Si-SiCl3 along with tBu3SiCl, tBu3Si-SitBu3, and tBu3SiH. After HPLC separation we isolated crystalline tBu3Si-SiCl3 from the eluate (retention time: τ = 39 min). During the work-up process further derivatives of tBu3Si-SiCl3 namely tBu3Si-Si(OH)3 (triclinic space group P-1), tBu3Si-Si(OMe)(OH)2 (monoclinic space group P21/c), and tBu3Si-Si(OMe)2(OH) (monoclinic space group P21/c) crystallize from the eluate. By the reaction of tBu3Si-SiCl3 with K in benzene we obtained the tetrasilatetrahedrane (tBu3Si)4Si4 (tetrasupersilyl-tetrahedro-tetrasilane) along with tBu3Si-SitBu3 and tBu3SiH. In contrast to the reaction in benzene treatment of tBu3Si-SiCl3 with K in thf yielded K[SitBu3]. We further investigated the cleavage of Si−Si bond by treatment of tBu3Si-SiCl3 with [nBu4N]Cl. Thereby tBu3SiCl and [nBu4N]2[Si6Cl14] were formed.
