6,7-Dihydro-2-pentafluorophenyl-5H-pyrrolo[2,1-c]-1,2,4-triazolium tetrafluoroborate（Cat No.:L027470）is a highly specialized, fluorinated heterocyclic ionic compound used primarily in advanced organic synthesis and catalysis. It features a fused pyrrolo-triazolium core with a pentafluorophenyl substituent at the 2-position, enhancing its electron-deficient character and stability. The tetrafluoroborate (BF₄⁻) counterion contributes to its solubility in polar solvents and thermal stability. This compound is particularly valuable as a precursor to N-heterocyclic carbenes (NHCs), which serve as ligands in metal catalysis or organocatalysis. Its structure allows precise control over electronic and steric properties in complex chemical transformations.
