Syntheses of (N → B)phenyl[N-alkylaminodiacetate-O,O′,N]boranes
摘要:
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 H-1, B-11 (for boron heterocycles), C-13 NMR, infrared spectroscopy and mass spectrometry. The H-1 NMR spectrum of compound 3 shows that it is a chiral molecule, its structure was determined by homonuclear decoupling experiments, H-1 NMR and HETCOR. The study of the intramolecular N-->B coordination by dynamic NMR afforded a Delta G double dagger value of 98.4 kJ mol(-1) for compound 3. Copyright (C) 1996 Elsevier Science Ltd
