all‐<i>cis</i>‐1,4,7,10‐Cyclododecatetraene—X‐Ray Structure Analysis and Photoelectron Spectrum

Compound 1, all-cis-1, 4, 7, 10-cyclododecatetraene, is not homoantiaromatically destabilized. In the crystal, it is present in a highly symmetric crown conformation. PE-spectroscopic measurements and model calculations show that there are no interactions between the double bonds.
