Monosubstituierte Cyclooctatetraene des Typs C8H7PR2 mit R = C2H5, t-C4H9 und C6H5 wurden erstmals dargestellt und chemisch sowie spektroskopisch charakterisiert. Die Temperaturabhangigkeit der NMR-Spektren der thermisch genugend stabilen tert-Butylverbindungen C8H7P(t-C4H9)2 und [C8H7P(t-C4H9)2CH3] I liefern Einblicke in die Dynamik der Doppelbindungsverschiebung, der Ringinversion und der Rotation um die (Ring-)C P-Bindung.

Monosubstituted cyclooctatetraenes of the type C8H7PR2 (with R = C2H5, t-C4H9. and C6H5) have been prepared for the first time and characterized both by their chemical properties and spectra. The temperature dependence of the NMR spectra of the tert-butyl compounds C8H7P- (t-C4H9)2 and [C8H7P(t-C4H9)2CH3] I, which exhibit satisfactory thermal stabilities, leads to detailed insights into the dynamics of the migration of the double bonds, of the ring inversion, and of the rotation around the (ring-)CP bond.
