Application

This potassium trifluoroborate salt is widely used as a coupling partner in palladium-catalyzed Suzuki-Miyaura reactions, enabling the formation of C-C bonds between aryl/vinyl halides and the cyclohexenyl group. It finds particular utility in medicinal chemistry for introducing saturated carbocycles into drug candidates. The compound’s stability makes it preferable to boronic acids in many applications. Researchers also employ it in the synthesis of functionalized cyclohexane derivatives for material science applications. Its trifluoroborate group offers improved handling characteristics compared to more sensitive boronic acid analogs.
