Pentafluorophenylboronic acid is widely used in organic synthesis as a versatile reagent, particularly in Suzuki-Miyaura cross-coupling reactions. It acts as a key intermediate for constructing complex molecules, including pharmaceuticals and agrochemicals, due to its ability to form stable boronate esters with diols and other functional groups. In materials science, it is employed to modify surfaces and create advanced polymers with specific properties. Additionally, it serves as a catalyst in certain chemical transformations, enhancing reaction efficiency and selectivity. Its electron-withdrawing pentafluorophenyl group makes it particularly effective in stabilizing reactive intermediates and improving reaction outcomes.
