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
