The invention relates to novel sulfur substituted norbornyl silicon compounds. Illustrated are trithianyl, dimercapto and mono-mercapto substituted norbornylsilicon compounds.

Sulfur containing norbornanyl silicon compounds

Polysulfide aryl silanes, mercapto aryl silanes, the hydrolyzates and condensates thereof, a process for the manufacture of said silanes, and their use as coupling agents in vulcanized rubber compounds.

Sulfur containing silane coupling agents

This invention relates to a method of reducing .beta.-cyanoethyltrialkoxysilane to the corresponding mercaptopropyltrialkoxysilane by reaction with sulfur.

Synthesis of mercapto-substituted silicon compounds

This invention is concerned with the manufacture of mercapto substituted silicon compounds by the decomposition of thio ether substituted silicon compounds. Acid catalysts, such as Friedel-Craft catalysts and halides of transition metals, greatly assist this decomposition.
