The syntheses of (N → B)phenyl[N-alkylaminodiacetate-O,O′,N]boranes (2 to 6) and their corresponding N-alkylaminodiacetic acids (7 to 10) are reported. All compounds (except 6) were characterized by 1H, 11B (for boron heterocycles), 13C NMR, infrared spectroscopy and mass spectrometry. The 1H NMR spectrum of compound 3 shows that it is a chiral molecule, its structure was determined by homonuclear decoupling experiments, 1H NMR and HETCOR. The study of the intramolecular N → B coordination by dynamic NMR afforded a ΔG? value of 98.4 kJ mol-1 for compound 3. Copyright
