Dibromosilane is a chemical compound from the group of silanes .

Extraction and presentation

Dibromosilane can be obtained by reacting monosilane with hydrogen bromide .

{\ displaystyle \ mathrm {2 \ SiH_ {4} +3 \ HBr \ {\ xrightarrow {AlBr_ {3}, ~ 100-200 ~ ^ {o} C}} \ SiH_ {3} Br + SiH_ {2} Br_ {2} +3 \ H_ {2}}}

In addition to other bromosilanes, the compound is also formed when silicon reacts with hydrogen bromide.

properties

Dibromosilane is a colorless, fairly highly refractive liquid that ignites in air and is very sensitive to moisture. It decomposes in water and ethanol.
