Abstract

The reaction of (R₂MeSi)₂MeSi-Li (2) [R=SiMe₃] with [ClMe₂Si]₂ yields the double-cored dendritic oligosilane [(RMe₂Si)₂ MeSi-SiMe₂]₂ (4). The structure of 4 was obtained from X-ray diffraction data, which verify a total of 16 silicon atoms in the molecule and a longest chain of 8 silicon atoms. 4 exhibits an absorption maximum in the near UV at 285 nm (E =5.6×10⁴), a wavelength that is significantly longer than that of the linear octasilane Si₈Me₁₈ and is the longest observed for structurally well-defined oligosilane dendrimers so far.
