Nuclear magnetic resonance studies of N-nitrosamines. Part 4. Barriers to rotation about the N–N bond for some cyclic compounds
Abstract
Information on the barrier to internal rotation about the N-nitroso-bond has been obtained for eight saturated cyclic N-nitrosamines by means of variable-temperature proton n.m.r. spectroscopy. Free energies of activation for the process are quoted and are discussed in terms of molecular conformation and group interactions.
