Organosilicon compounds active hydrogen

Recent studies on the direct reaction of elemental silicon with alkyl chlorides such as methyl chloride, activated alkyl chlorides, polychloro-methanes, (chloromethyl)silanes, (dichloromethyl)silanes, etc. are summarized in this review. In the direct reaction of elemental silicon with activated alkyl chlorides and polychloromethanes, the decomposition of the reactants can be suppressed and the production of polymeric carbosilanes reduced by adding hydrogen chloride to the reactants. These reactions provide a variety of new organosilicon compounds containing Si-H and Si- Cl functionalities, which should find considerable application in the silicone industry. 

The determination of active hydrogen bonded to a silicon atom was described [101], based on hydrolysis of an organosilicon compound with potassium hydroxide for 15 sec with liberation of an equivalent amount of hydrogen. The determination of hydrogen in boranes by acid hydrolysis has been discussed [102].
