Synthese homokonjugierter Polyene: 2,4-Dimethylenbicyclo[3.2.0]oct-6-en und 2,5-Dimethylenbicyclo[4.2.0]non-7-en

Hans-Dieter Martin; Constanze Heller

The synthesis of the two homoconjugated trienes has been achieved by cleavage of the strained σ-bonds of suitable cyclopropane and cyclobutane precursors. Ionization energies are discussed.
