Hexamethyldisilazane as an Acylation Generator for Perfluorocarboxylic Acids in Quantitative Derivatization of Primary Phenylalkyl Amines Confirmed by GC/MS and Computations
derivatization processes were determined by gas chromatography/mass spectrometry. Reaction conditions were optimized depending on reagents’ molar ratios, solvents, and temperatures applied. The new acylation method, in comparison to the traditional ones, obtained with trifluoroacetic anhydride, heptafluorobutyric anhydride, and N-methyl-bis(trifluoroacetamide), offers numerous advantages.

The first general method for the reducing reagent-free, biomimetic transformation of perfluorocarboxylic acids to the α,α-dihydroperfluoroalkyl amines is reported. High chemical yields and simplicity of the experimental procedure render this method immediately useful and synthetically superior to the conventional approaches relying on application of reducing reagents.
