2,2,2-Trifluoroacetamide used in a convenient alternative to the Gabriel synthesis of primary amines from halides by N-alkylation followed by cleavage of the readily-hydrolyzed trifluoroacetyl group and for improved N-alkylation under phase-transfer conditions allowing successive alkylation with different alkyl groups.

Has been used in a convenient alternative to the Gabriel synthesis of primary amines from halides by N-alkylation followed by cleavage of the readily-hydrolyzed trifluoroacetyl group: Synthesis, 941 (1984). For improved N-alkylation under phase-transfer conditions allowing successive alkylation with different alkyl groups, see: Synth. Commun., 18, 791 (1988). The method has been further extended by the use of ɑ-bromo esters to provide a high yielding route to ɑ-amino acids: J. Org. Chem., 56, 420 (1991):
