Representatives of the homologous series of α,ω- diallylpermethyloligosilanes were synthesized for the first time by the reaction of α,ω-dichloropermethyloligosilanes Cl(Me2Si) nCl (n = 2-6) with allylmagnesium chloride. Fragmentation of α,ω-diallylpermethyloligosilanes under electron impact ionization was studied by mass spectrometry.
Homoconjugation in allyl silicon derivatives

New diallyl derivatives of mono- and disilane were obtained and characterized. Fluorescence, 1H, C, and 29Si NMR, as well as IR and Raman spectroscopy were used to show the presence of intramolecular donor-acceptor β-coupling between the silicon atom and the allyl groups, which is realized directly through space by the homoconjugation mechanism (i.e. direct conjugation between vacant 3d orbitals of the silicon atom and the allyl π bonds, not involving σ orbitals of the allyl methylene groups).
