Application

This potassium trifluoroborate salt is primarily employed as a stable alternative to boronic acids in palladium-catalyzed cross-coupling reactions for biaryl formation. The MEM-protected trifluoroborate moiety demonstrates enhanced stability toward protodeboronation while maintaining high reactivity in Suzuki-Miyaura couplings. It finds particular utility in synthesizing complex molecules where traditional boronic acids might decompose under basic conditions. Researchers value this compound for its compatibility with both aqueous and organic reaction media, enabling versatile synthetic strategies in medicinal chemistry and materials science applications.
