摘要：

The thermodynamically and kinetically stable peralkyloctasilacubane 1 is formed in the reaction of RSiCl3 (R = CMe2CHMe2) with Na. The orange-red compound is soluble in hydrocarbons and was characterized by spectroscopy and X-ray crystallography. Both its long-wavelength electronic transition in the UV/VIS spectrum at lambda almost-equal-to 500 nm and its low oxidation potential found by cyclic voltammetry at 0.43 V-unusual values for cyclopolysilanes-are traced back to the highly strained Si8 framework.
