Abstract
The results of variable-temperature 1H n.m.r. spectroscopic investigations, including both multiple irradiation experiments and qualitative measurements of nuclear Overhauser effects, on D-(2)-PhCH2NH3ClO4 indicate that the conformation (Ha/Hc) in which the phenyl ring in the cation is oriented over one of the 1,3-dioxan rings in D-(2) becomes increasingly preferred in CD2Cl2 solution as the temperature is lowered.Keywords
