A perfluorinated benzoic acid building block

Forms organometallic complexes for catalysts and APIs


Pentafluorobenzoic acid (CAS number 602-94-8), also known as perfluorobenzoic acid, is a benzoic acid compound that is fully substituted with five fluorine groups on the benzene ring. Being a perfluorinated compound, pentafluorobenzoic acid is considered to be electron deficient. It finds application in the exploration of the reaction mechanism involved in indolyl 1,3-heteroatom transposition reactions.

Pentafluorobenzoic acid can coordinate to metal centres, forming organometallic complexes. It acts as a bidentate ligand for the preparation of 2D coordination polymers with copper and fullerene. Density functional theory (DFT) calculation reveals that a pentafluorobenzoic acid-copper(I)-fullerene complex possesses a narrow bandgap of 0.95 eV. Additionally, by taking the advantage of the electron deficiency, pentafluorobenzoic acid is utilized for the study of the π-stacking interaction in titanium salalen catalysts.
