    摘要: 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.

    摘要: 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.
