General Description

Chloro(ethoxy)dimethylsilane is a chemical compound with the molecular formula C4H11ClOSi. It is a colorless liquid at room temperature and is primarily used as an intermediate in the production of various silicon-based compounds. It is a versatile reagent in organic synthesis, particularly in the creation of silane and silicon-based polymers. Chloro(ethoxy)dimethylsilane is also used as a surface modifier in the production of silicones, and as a crosslinking agent in the manufacture of elastomers and resins. It is important to handle and store this chemical with caution, as it is flammable and can cause irritation to the skin, eyes, and respiratory system upon contact or inhalation.

SYNTHESIS OF ORGANO CHLOROSILANES FROM ORGANOSILANES

The invention relates to a process for the production of chlorosilanes by subjecting one or more hydndosilanes to the reaction with hydrogen chloride in the presence of at least one ether compound, and a process for the production of such hydndosilanes serving as starting materials.

Lewis Base Catalyzed Selective Chlorination of Monosilanes

A preparatively facile, highly selective synthesis of bifunctional monosilanes R2SiHCl, RSiHCl2 and RSiH2Cl is reported. By chlorination of R2SiH2 and RSiH3 with concentrated HCl/ether solutions, the stepwise introduction of Si?Cl bonds is readily controlled by temperature and reaction time for a broad range of substrates. In a combined experimental and computational study, we establish a new mode of Si?H bond activation assisted by Lewis bases such as ethers, amines, phosphines, and chloride ions. Elucidation of the underlying reaction mechanisms shows that alcohol assistance through hydrogen-bond networks is equally efficient and selective. Remarkably, formation of alkoxysilanes or siloxanes is not observed under moderate reaction conditions.

PROCESS FOR THE PREPARATION OF HALOALKYLALKOXYSILANCS AND HALOALKYLHALOSILANES

This invention involves a process for the preparation of haloalkylalkoxysilanes and haloalkylhalosilancs. The process comprises reacting an alkoxyhydridosilane or a halohydridosilanc silane with an alkenylhalide compound in the presence of a catalytic amount of an iridium containing catalyst. When a halohydridosilane is the silane rcactant. the resulting haloalkylhalosilane may be alkoxylatcd by reaction with a C1-C6, alcohol, In another aspect of the invention, the reacting is conducted under a reduced oκygen atmosphere to improve the catalyst activity and the yield of the resulting haloalkylhalosilane or halυalkylalkυx vsi lane.
