    Description / Table of Contents: Stereochemistry of Bicyclic Ring Compounds, XIII; Stereochemistry of Hydrindane and its Derivatives, V. α-HydrindanolesThe four isomeric α-hydrindanoles are described; older specifications are corrected. The kinetics of the alcoholysis of their tosylates and of the alkaline saponification of three acidic succinates are investigated. cis- and trans-Δ1,2, -Δ1,8 and -Δ8,9-hexahydroindenes are prepared and characterized by their oxidation rates with peracids. The configurations of both cis-β-hydrindanoles are established via cis-hydrindene-1,2-oxide.
    Notes: Die vier isomeren α-Hydrindanole 1-4 nebst Derivaten werden beschrieben, wobei ältere Angaben berichtigt werden. Die Kinetik der Äthanolyse ihrer Tosylate und die alkalische Verseifung von drei sauren Succinaten werden untersucht. cis-und trans-Δ1.2, -Δ1.8 -und -Δ8.9-Hexahydroinden werden dargestellt und durch die Geschwindigkeit ihrer Oxydation mit Persäure charakterisiert. Über das cis-Hydrinden-oxid-(1.2) werden die Konfigurationen der beiden cis-β-Hydrindanole ermittelt.

    Description / Table of Contents: Configurations and 1H-NMR Spectra of Tertiary Bicyclo[2,2,1]heptyl-(2) CompoundsThe configurations of 20 tertiary substituted norbornyl compounds are discussed in connection with the NMR spectra of the methyl groups. The observed shift and band width (table 1) have been correlated to the steric environment, which is reflected by the solvolysis kinetics of related derivativesDie Solvolysereaktionen und deren Kinetik werden getrennt mitgeteilt. . The configurations can be assigned spectroscopically using appropriate steric models.
    Notes: Von 20 tertiären Verbindungen des Norbornan-Typs werden die Konfiguration und die NMR-Signale der Methylgruppen untersucht. Die beobachteten Verschiebungen und Halbwertsbreiten (Tab. 1) lassen sich zu den sterischen Verhältnissen, wie sie sich in der Solvolysekinetik entsprechender DerivateDie Solvolysereaktionen und deren Kinetik werden getrennt mitgeteilt. äußern, in Beziehung setzen. Unter Berücksichtigung sterischer Modelle kann die Konfiguration spektroskopisch zugeordnet werden.
