  • Method of producing cyclohexasilane compounds
    Patent number: 8975429
    Abstract: A method of preparing a cyclohexasilane compound from trichlorosilane is provided. The method includes contacting trichlorosilane with a reagent composition to produce a compound containing a tetradecahalocyclohexasilane dianion, such as a tetradecachlorocyclohexasilane dianion. The reagent composition typically includes (a) tertiary polyamine ligand; and (b) a deprotonating reagent, such as a tertiary amine having a pKa of at least about 10.5. Methods of converting the tetradecahalocyclohexasilane dianion-containing compound to cyclohexasilane or a dodecaorganocyclohexasilane are also provided.

  • Method of producing polyalkylated oligoalkylenepolyamines
    Patent number: 8658829
    Abstract: A method of preparing polyalkylated oligoalkylenepolyamines is provided. The method includes contacting oligoalkylenepolyamine with a reagent composition comprising (a) alkyl bromide and/or alkyl chloride; (b) a basic agent; and (c) iodide salt. The alkylation reaction may be carried out in a polar, aprotic organic solvent.
