  Synthesis, structure, and reactivity of 1,ω-bis(pseudo-pentacoordinated) 1,ω-difluoro-oligosilanes bearing 8-(dimethylamino)-1-naphthyl groups

  摘要：

  1,omega-Bis[8-(dimethylamino)-1-naphthyl]-1,omega-difluorotrisilane 1 (omega = 3) and tetrasilane 2 (omega = 4) have been prepared. The X-ray crystallography of dl-1 and meso-1 shows unsymmetrical structures having different coordination modes at the two terminal silicons. The unsymmetrical nature of the structure of 1 can also be observed by solid state CP/MAS NMR spectroscopy. Trisilane 1 is thermochemically labile and undergoes facile degradation at 145 degrees C, but is photochemically stable under irradiation of its benzene solution with a 6 W-low pressure mercury lamp, making a sharp contrast to the behavior of their tetracoordinate counterparts containing naphthyl groups which are thermochemically stable but photochemically active. Tetrasilane 2 undergoes a Pd(0)-catalyzed alpha-elimination of a fluorosilane moiety at the two pseudo-pentacoordinated silicon atoms to form the 1,2-difluorodisilane, which is trapped with diphenylacetylene as a double-silylation product.

  The syntheses of the trisilanes (X3Si)2SiMe2, X = H, F, Cl, Br, I, OMe, starting from (Ph3Si)2SiMe2 are described. The reaction of 1,1,1,3,3,3-hexaphenyl-2,2-dimethyltrisilane with triflic acid, followed by a treatment with LiF or reduction with LiAIH4, leads to the trisilanes (HPh2Si)2SiMe2, (H2PhSi)2SiMe2, HPh2SiSiMe2SiH2Ph, (FPh2Si)2SiMe2, (F2PhSi)2SiMe2 and FPh2SiSiMe2SiF2Ph.
