Usage

General Description

Triethylbromosilane is a chemical compound with the molecular formula C6H15BrSi. It is a colorless to yellow liquid with a pungent odor, and it is highly reactive and flammable. Triethylbromosilane is commonly used as a reagent in organic synthesis, particularly for the production of organosilicon compounds. It is also used as a crosslinking agent in the manufacture of silicone polymers and as a source of bromine in chemical reactions. However, it is important to handle and store triethylbromosilane with caution due to its hazardous nature and potential for releasing toxic fumes.

Synthesis of bromohydrosilanes: Reactions of hydrosilanes with CuBr2 in the presence of CuI

Reactions of hydrosilanes, R4-nSiHn (R = alkyl or phenyl, n = 1-3), with 2 equiv of CuBr2 in the presence of a catalytic amount of CuI led to selective replacement of an H-Si bond with a Br-Si bond giving R3SiBr, R2SiHBr, or RSiH2Br, while treatment of R2SiH2 and RSiH3 with 4 equiv of the reagent produced R2SiBr2 and RSiHBr2, respectively. Similar reaction of HEt2SiSiEt2H afforded HEt2SiSiEt2Br.

Deoxygenative reduction of carbon dioxide to methane, toluene, and diphenylmethane with [Et2Al]+ as catalyst

The strong Lewis acid [Et2Al]+ catalyzes the reduction of carbon dioxide with hydrosilanes under mild conditions to methane. In benzene solution, the side products toluene and diphenylmethane are also obtained through Lewis acid catalyzed benzene alkylation by reaction intermediates. Copyright

PdCl2 and NiCl2-catalyzed hydrogen-halogen exchange for the convenient preparation of bromo- and iodosilanes and germanes

Bromination and iodination of hydrosilanes and germanes were studied. Treatment of hydrosilanes with an excess of ethyl, propyl, or allyl bromide in the presence of a catalytic amount of PdCl2 or NiCl2 gave bromosilanes in good to high yield by hydrogen-halogen exchange. By using methyl, propyl, or allyl iodide as the iodine source, similar iodination of hydrosilanes was readily performed. Halogenation of hydrogermanes also proceeded by similar treatment.
