✦ Synopsis

The fast atom bombardment-induced mass spectrometric behaviour of four Ñuorinated a-amino acids was studied in detail with the aid of metastable ion studies and accurate mass measurements. Comparison with the behaviour of unÑuorinated analogues suggests that the presence of Ñuorine makes the carbonylic oxygen the most prone to protonation. This hypothesis was conÐrmed by AM1 semiempirical calculations which indicate that the carbonylic oxygen of the carboxyl group exhibits, in the case of Ñuorinated compounds only, the highest proton affinity.

Previous studies have demonstrated that the interaction of carboxylic acids with aryl amines produces free radicals that can initiate the polymerization of acrylic monomers. N-Aryl-a-amino acids (NAAA) represent a special class of this type of initiator that combines in one molecule the carboxylic a
