Abstract

The reaction of (ButCH2) 2SiCl2 with Li in tetrahydronfuran gave the peralkylcyclotrisilane, hexaneopentylcyclotrisilane [(ButCH2) 2Si] 3 (1), which showed a uv 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 ...
