Verwenden2,2-Difluoroethylamine (DFEA) is an ESI-compatible buffering reagent whose conjugate acid has a pKa of 7.2, providing buffering capacity at physiological pH[1]. 2,2-Difluoroethylamine serves as a nucleophile in Ni-catalyzed C–N cross-couplings with aryl electrophiles, including N-arylation of fluoroalkylamines and competition studies against other heteroatom-containing nucleophiles[2].
