Contributions to the Chemistry of Silicon—Sulfur Compounds. XXVII. The Insertion of Sulfur into the Silicon—Hydrogen Bond of Arylsilanes. The Preparation of Arylsilanethiols and Aryldisilthianes

The reaction of arylhydrosilanes with sulfur has been studied. The influence of temperature, solvent, catalysts and reagents ratio were considered. The relative reaction rates of hydrosilanes have been evaluated and reaction mechanism discussed. This insertion yields silanethiols which after following condensation yield disilthianes.
