A highly efficient route for the preparation of the sterically overcrowded oligosilyl anion TBTSLi(THF)4 (3) TBTS=Si[Si(SiMe3)2Me]3} in a large scale is reported. The reactions of HSiCl3 and SiCl4 with 3 do not give coupling products, instead they produce TBTSH and TBTSCl, probably as a result of steric interactions. On the contrary, PhSiF3 and SiF4 can be reacted with 3 to give TBTSSiF3 (5) and

A number of various branched heptasilanes [(Me3Si)2MeSi]2MeSiX (2: X=Ph; 3: X=Me; 6: X=Br; 7: X=I; 8: X=Cl; 9: X=F; 10: X=OH) bearing two (Me3Si)2MeSi groups as well as branched decasilanes [(Me3Si)2MeSi]3SiX (12: X=H; 13: X=Br; 14: X=Cl; 15: X=F; 16: X=OH) bearing three (Me3Si)2MeSi groups at one silicon centre were synthesized. The structures of the compounds prepared were elucidated on the basis
