    摘要: Halogenosilanes are prepared from an organohalogenosilane and an organopolysiloxane as the starting materials by subjecting them to an intermolecular redistribution reaction in the presence of a monohydrochloride of a hexaalkylphosphotriamide. The thus prepared halogenosilanes, which are different from the starting halogenosilane reactant, are very useful in the silicone industry.

    摘要: A novel class of compounds, tris(triorganosilylalkyl) phosphites, represented by the general formula [R.sub.3 Si(CH.sub.2).sub.n O].sub.3 P where R is a monovalent hydrocarbon group and n is 1, 2 or 3. These novel compounds may be synthesized by dehydrochlorination reaction between a triorganosilyl-substituted alkanol and phosphorus trichloride in the presence of a tertiary amine. They have useful values as agricultural chemicals because of their biological activities and also as intermediate compounds in the preparation of certain medicines and chemicals.
