The synthesis of the sterically overcrowded oligosilyl anions tris[methylbis(trimethylsilyl)sily1]silylpotassium [TBTS-K], -lithium [TBTS-Li] (2) and heptakis(trimethylsilyl)tetrasilacyclobutylpotassium [HTSB-K] (9) is reported. The new oligosilanes, TBTS-SiF3 (9,TB TS-SiF2Ph (6) and TBTS-SiH20Ph (7) were readily prepared by treatment of 2 with SiF4, PhSiF3 and (PhO)3SiH, respectively. The molecular structure of 6 has been derived from X-ray diffraction data. The reaction of 9 with SiF4, PhSiF3 and PhSiH2Cl led to the formation of the cyclic oligosilanes HTSB-SiF3 (lo), HTSB-SiF2Ph (11) and HTSB-SiH2Ph (12), respectively.
