In a preceding communication the hemi-acylal formation leading to a fixed chair-boat form 5 in bicyclo[3.3.l]nonanes has been discussed2). Aiming at a better understanding of this unusual phenomenon 31 two hydroxyketones capable of formation of the acetal derivative B were synthesized in which the e
## Abstract Carbon‐13 NMR spectra of solid polycrystalline bicyclo[3.3.1]nonan‐9‐one and adamantanone have been measured at 315K. The relatively narrow ^13^C linewidths observed for these solids, together with measured spin‐lattice relaxation times, indicate that both these solids are orientational
## Abstract Die Synthesen der Titelverbindungen **5** und **7** sowie einiger anderer Bicyclo[3.3.1]nonan‐Derivate werden beschrieben. Die γ‐Effekte der Substituenten auf die ^13^C‐chemische Verschiebung lassen sich gut durch halbquantitative Abschätzung der Torsionswinkel des betreffenden Molekülf
