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
的(BU反应吨CH 2)2的SiCl 2与Li在tetrahydronfuran得到peralkylcyclotrisilane,hexaneopentylcyclotrisilane [(卜吨CH 2)2的Si] 3(1),其表现出UV吸收最大值λ最大在310nm; 在烃溶剂中照射(1)得到过烷基二ilene,四新戊基二ilene(Bu t CH 2)2 Si Si(CH 2 Bu t)2,显示为有色化合物(λmax400nm)是由于存在作为发色团的Si- Si键骨架。
