Anionic ring-opening polymerization of a seven-membered cyclic carbonate, 1,3-dioxepan-2-one ( 1), was carried out to observe that the higher the polymerization temperature and lower the initial monomer concentration were, the lower the yield and molecular weight, and wider the molecular weight dist
## Abstract ^13^C NMR spectra of six epimeric substituted 4βhydroxypiperidines and two corresponding piperidines were recorded. Substituent parameters for equatorial methyl, __gem__βdimethyl, equatorial hydroxy and axial hydroxy groups were calculated from the ^13^C chemical shifts of these compoun
