Used as a reagent in Suzuki-Miyaura cross-coupling reactions to introduce vinyl bromide functionality in organic synthesis. Its stability and reactivity make it suitable for constructing complex alkenes, particularly in pharmaceutical and agrochemical intermediates. The trifluoroborate group enhances handling and shelf life compared to more sensitive boronic acids, while the bromoalkene moiety allows further functionalization via cross-coupling or cyclization reactions. Commonly applied in the synthesis of styrene derivatives and conjugated systems for materials science and bioactive molecule development.
