  • Description: Polygons: [8]Circulenes were easily prepared by Pd‐catalyzed annulations of tetraiodotetraphenylenes with alkynes. Their saddle‐shaped structure with an [8]radialene character was identified by X‐ray crystallography. Similar to 1,3,5,7‐cyclooctatetraene, they have a tub‐shaped eight‐membered ring, but all of the bond lengths and bond angles are almost equal. Variable‐temperature NMR investigations showed interesting dynamic behavior.
