名称:
μ-Methylen-bis[chlor-bis(trimethylsilyl)methylalan] {(Me3Si)2CH(Cl)AlCH2Al(Cl)CH(SiMe3)2} mit einer Heteroadamantanstruktur
摘要:
The title compound 1 is formed by melting the peralkylated R2Al-CH2-A1R2 (R = CH(SiMe3)2) with the tetrachloro derivative Cl2Al-CH2-AlCl2 at 125-degrees-C. Crystal structure analysis reveals an Al-Cl bridged dimer with a heteroadamantane structure. Reaction of 1 with neopentyl lithium or trimethyl-silylmethyl lithium yields only the dismutation products Al[CH(SiMe3)2]R2 (R = CH2CMe3 and CH2SiMe3). From the missing methylene bridge oligomeric or polymeric species are formed presumably; these could not be isolated as pure compounds.
