Synthesis and structures of simple (silylmethyl)(methyl)ethers
Mitzel, Norbert W.

The compound Cl3SiCH2OCH3 was prepared by reacting ClCH2OCH3 with the Cl3SiH/NEt 3 reagent. H3SiCH2OCH3 and F 3SiCH2OCH3 were synthesized from Cl 3SiCH2OCH3 by reduction with LiAlH4 and by fluorination with SbF3, respectively. The crystal structures of the low-melting compounds H3SiCH2OCH3 and F3SiCH2OCH3 were determined by X-ray diffraction of in situ grown crystals. Both compounds do not show any observable β-donor-acceptor interactions, but behave structurally like usual dialkylethers or silanes, as is obvious from the structural parameters in H3SiCH2OCH3 (3SiCH2OCH 3 (SiCO 107.1(1), COC 111.2(2)°). Earlier postulates of Si?O interactions in compounds with SiCO units could thus not be confirmed on a structural basis.
Reaction of Hydrogen Peroxide with Organosilanes under Chemical Vapour Deposition Conditions

When a stream of vapour at low pressure which contained a mixture of H2O2 with an organosilane, RSiH3 (R = alkyl or alkenyl), impinged on a silicon wafer, deposition of oxide films of nominal composition RxSiO(2-0.5x), where x 3 or higher alkenyl groups. or higher alkenylgroups. Possible mechanism for the Si-C bond cleavage reaction are discussed, with energetic rearrangement of radical intermediates of type Si(H)(R)(OOH)' being favoured.
1H NMR Study of some Substituted Acyclic Silaethanes, 2-Silapropanes and 2-Methyl-2-Silapropanes and their Rotameric Populations around the Si-C Bond

Three series of substituted silaalkanes, (i) SiH3CH2X, (ii) MeSiH2CH2X and (iii) Me2SiHCH2X, have been prepared (X=Cl, Br, I, NMe2, OMe, SMe), and the shifts and coupling constants extracted from their 1H NMR spectra.Coefficients averaged over three rotameric states can be obtained from the first series which are used for the correction of coupling constants resulting from the presence of the electronegative substituents X.With the aid of the Karplus-Conroy angular dependence of the interproton coupling constants in silaethane fragments, corrected for electronegative substitution, approximate rotameric population in series ii and iii were obtained.Except for X=NMe2, there is always a preference for a synclinal X/CH3 relationship, even for sandwiched situation (series iii).
