Abstract: A method for preparing an organosilane functionalized in the 3 position includes reacting an allyl compound (H2C═CH—CH2X) with a silane (R2R3R4SiH) in a reaction column under a pressure between 1 bar and 25 bar, in the presence of a heterogeneous platinum catalyst. The silane reactant is present in the reaction column, and introduced into the reaction column, in a stoichiometric excess with respect to the allyl compound. The reaction column preferably includes a reaction zone, a first separation zone located above the reaction zone, and a second separation zone located below the reaction zone, wherein a first product exits the reaction zone and enters the first separation zone, and a second product exits the reaction zone and enters the second separation zone. Distillation occurs simultaneously with the reaction in the reaction chamber.

Abstract: Oligomeric organosilanepolysulfanes which are built up from the three structural units A and/or B and/or C, in which Y=H, CN, —(CH2)nSiRR1R2; n=1-8, R, R1, R2 and R3, independently, represent H, (C1-C4)alkyl, (C1-C4)alkoxy, halogen or a OSiR1R2R3 group; x, as a statistical average, is 1-6, z, as a statistical average, is 2-6, n is 1-8 and o, p and q are each a whole, positive number between 1 and 40 where o+p+q may be ≧2 and <40, with the proviso that at least one structural unit A or B is present, and their use in rubber mixtures and to produce molded items, in particular pneumatic tires.

Abstract: Sulfanylsilanes of the formula X1X2X3Si—A—S—SiR1R2R3 are prepared by reacting mercaptosilanes of the formula X1X2X3Si—Alkyl—SH with chlorosilanes Cl—SiR1R2R3. They are used as coupling agents in rubber mixtures.

Abstract: A process for joining two solid bodies, in particular of silicon. via the substantially smooth surfaces that have first of all been coated with a monomolecular layer of a sulfur-containing organosilane, and the resultant solid bodies, which may be used in microelectronics or micromechanics.

Abstract: A process for the preparation of organosilanes functionalized in the 3-position, by the reaction of suitable allyl compounds with hydrogen silanes, using platinum catalysts having one or more sulfur-containing ligands.

Abstract: A method for the production of organosilanes functionalized in 3-position by reacting suitable allyl compounds with hydrogen silanes in the presence of a multielement catalyst containing platinum and at least one other element.

Abstract: Silylalkylthiols are produced by reacting silylalkylsulfanylsilanes with water. The silylalkylsulfanylsilanes used as starting products can be produced by reacting bil-silylalkylpolysulfanes or bis-silylalkyldisulfanes with alkali metal and chlorosilanes.
