Application

This triflate ester is widely used as an electrophilic coupling partner in palladium-catalyzed cross-coupling reactions to construct biaryl systems. It serves as a precursor for synthesizing fluorinated pharmaceutical intermediates due to the enhanced metabolic stability imparted by the trifluoromethyl group. Researchers also employ it in polymer chemistry to introduce aromatic ketone functionalities into backbone structures.
