Abstract
Reaction of [HC(SiMe2H)(3)] with [(CH3)(2)-CH](2)NLi in tetrahydrofuran. af forded [LiC(SiMe2H)(3]) 2THF (1) in excellent yield. Reactions of I with Me 3SiCl, MeSiHCl2, HSiCl3 and MeSiCl3 at -78 degrees C gave [Me3SiC(SiMe2H)(3 )] (2), [(HMeClSi)C(SiMe2H)(3)] (3), [(HCl2Si)C(SiMe2H)(3)] (4), and [(MeCl 2Si)C(SiMe2H)(3)] (5), respectively. At room temperature, reaction between 1 and SiCl4 in toluene resulted in multiple products, including a new highl y substituted 1,3-disilacyclobutane [Me2SiC(SiMe2H)(2)](2) (6). 6 was isola ted in, moderate yield from reaction, of 1 with 2 equiv of SiCl4.
