Used as a reagent in Suzuki-Miyaura cross-coupling reactions to introduce a (Z)-2,3-dibromopropenyl group into organic molecules. Its primary application is in the synthesis of complex alkenes, where retention of the Z-configuration is critical. The trifluoroborate moiety enhances stability and handling compared to the corresponding boronic acid, while still allowing efficient transmetalation under mild conditions. It is particularly useful in pharmaceutical and agrochemical research for constructing stereodefined building blocks. The presence of bromine atoms allows for further functionalization via additional cross-coupling or substitution reactions, enabling rapid diversification of molecular structures.
