Multinuclear NMR Spectra, 1H-T1 Relaxation, Conformational Behavior, and Intramolecular Hδ-····δ+H Contacts of N−Borane Cyclic Adducts in Solution
摘要:
The VT H-1 NMR and H-1-NOESY spectra revealed "frozen" envelope conformations in solutions of 1 and 2 with the BR3 groups in equatorial positions. The H-1-T-1 relaxation measurements provided determinations of the intramolecular proton-hydride contacts in solutions of adducts 1 and 8.
