Abstract
The reaction of (ButCH2)2SiCl2 with Li in tetrahydronfuran gave the peralkylcyclotrisilane, hexaneopentylcyclotrisilane [(ButCH2)2Si]3(1), which showed a u.v. absorption maximum λmax at 310 nm; irradiation of (1) in a hydrocarbon solvent afforded the peralkyldisilene, tetraneopentyldisilene (ButCH2)2 SiSi(CH2But)2, which was shown to be a coloured compound (λmax 400 nm) owing to the presence of the SiSi bond framework which acts as a chromophore.Keywords
