Improved synthetic route to potassium silyl using crown ethers, potassium, and silane and its use to prepare methylsilane and disilylmethane

The time for the reaction between K and SiH4 in glyme is reduced from months to hours by addition of 18-crown-6 to form SiH3.The usefulness of the reaction to prepare the SiH3- anion as a synthetic intermediate is demonstrated by the reaction of SiH3 with CH3I and CH2Cl2 to prepare H3SiCH3 and (H3Si)2CH2, respectively.The rate of the reactions between K and GeH4 is also increased but not as dramatically with the addition of 18-crown-6 to form GeH3.

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.

Synthetic Pathways to Disilylmethane, H3SiCH2SiH3 and Methyldisilane, CH3SiH2SiH3

Disilylmethane is available in a four-step synthesis starting with phenylsilane.This is converted into chlorophenylsilane by HCl/AlCl3.The reaction of PhSiH2Cl and bibromomethane with magnesium in tetrahydrofuran affords bis(phenylsilyl)methane, which yields bis(bromosilyl)methane by treatment with anhydrous hydrogen bromide. (BrH2Si)2CH2 is converted into disilylmethane by reduction with LiAlH4 in a two-phase system using a phase-transfer catalyst. - Methyldisilane is available by alkylation of monohalodisilane, XSi2H5 (X=Cr, Br), with methyllithium in a high-boiling ether or by silylation of bromomethylsilane with silylpotassium.Due to secondary silylation reactions the overall yields of methyldisilane are low in all cases.
