ResumoThe strain energy of some cyclenes with one double bond in the ring has been calculated as a function of various geometric parameters. The minimum energy forms for trans-cyclooctene and for trans-cyclononene are characterized by a twisting angle at the double bond of 17–18°. The most stable configuration for cis-cyclononene and cis-cyclodecene is like that found for cis-cyclooctene in previous work. In trans-cyclodecene the minimum energy form with an axis of symmetry is angular strainless and remarkable for its flexibility.
