Applications

Boron tribromide is used as a reactant for luminescent polystyrene derivatives with sterically protected carbazolylborane moieties, high-quality boron-doped graphene via Wurtz-type reductive coupling reaction and micrometer-sized organic molecule-DNA hybrid structures. It is also used in bromination and cyclization reactions to prepare cyclopenta[1,3]cyclopropa[1,2-b]pyrrolizin-8-one. It acts as a liquid boron source used in p-type deposition processes.

Notes

Moisture sensitive. Reacts violently with water. Incompatible with alcohols, alkali metals, aluminum, sodium oxides and strong bases.
