| Abstract: | The synthesis and structural characterization of bulkier variations of the very common organometallic compound MSi(SiMe3)3, namely MSi(SiMe3)(SiPh3)2 3 and MSi(SiPh3)3 [M = Li ( 1 ), K ( 5 )] are presented, which can be synthesized via a step by step exchange of SiMe3 groups by bulkier SiPh3 groups. This synthetic route is high selective and is performed in good yields via the silanes Si(SiMe3)2(SiPh3)2 ( 2 ) and Si(SiMe3)(SiPh3)3 ( 4 ). Additionally, the corresponding silanes HSi(SiMe3)(SiPh3)2 ( 6H ) and HSi(SiPh3)3 ( 7H ) are obtained via the reaction of 3 and 5 with aqueous HCl, respectively. Oxidation of 6H with CCl4 gives the chlorsilane Cl‐Si(SiMe3)(SiPh3)2 ( 6Cl ). The bulkiest chlorsilane Cl–Si(SiPh3)3 ( 7 ) is obtained by the reaction of 5 with ECl2 (E = Sn, Pb). |
