Synthesis of vinyl trifluoroborates
The palladium-catalyzed cross-coupling reaction of potassium
alkenyltrifluoroborates with aryl and heteroaryl halides and triflates
proceeds readily with moderate to excellent yields.

1-Trifluoroboratoalkenes are oxidized by dioxirane, providing air-stable, crystalline oxiranyltrifluoroborates without cleavage of the carbon-boron bond. The first Suzuki-Miyaura coupling of an epoxytrifluoroborate has been accomplished.
