Synthesis and characterization of new aromatic-group substituted silanes bearing tris (trimethylsilyl)methyl bulky groups

Reaction of the Grignard reagent, p-ClC6H4MgCl, with SiCl4 in toluene gave (p-ClC6H4) 2SiCl2, which was treated with KHF2 to give (p-ClC6H4)2SiF2 (1). Reaction of the latter with [(Me3Si)3C]Li in THF leads to the preparation of [(Me3Si)3C](p-ClC6H4) 2SiF (2). Treatment of (2) with LiAlH4 gave [(Me 3Si)3C](p-ClC6H4)2SiH (3) and [(Me3Si)3C](p-ClC6H4)(C 6H5)SiH (4). [(Me3Si)3C](p-ClC 6H4)SiCl2 (5) was also prepared from the reaction of (p-ClC6H4)SiCl3 with [(Me 3Si)3C]Li in a similar manner. The new highly sterically hindered organosilicon reagents (2) to (5) have been fully characterized by IR, 1H and 13C NMR, and mass spectrometry as well as elemental analysis.
