Description
Potassium n-pentyltrifluoroborate (CAS No. 872054-60-9) is a high-purity organoboron compound with the molecular formula C5H11BF3K. This potassium salt of n-pentyltrifluoroborate is a stable, air-sensitive reagent widely used in cross-coupling reactions, particularly in Suzuki-Miyaura couplings, due to its excellent reactivity and selectivity. Its IUPAC name, potassium;trifluoro(pentyl)boranuide, reflects its structural composition, featuring a pentyl group attached to a trifluoroborate anion balanced by a potassium cation. This compound is supplied as a white to off-white crystalline powder, typically stored under inert conditions to maintain stability. With a molecular weight of 186.05 g/mol, it is soluble in polar organic solvents such as THF, DMF, and DMSO, making it ideal for homogeneous catalytic systems. Researchers and synthetic chemists value this reagent for its robustness in forming C-C bonds under mild conditions, enabling the synthesis of complex organic frameworks.
