Perethynylated dehydroannulenes are accessible by oxidative Hay coupling of a tetraethynylethene with a free cis ‐enediyne unit. Besides a yellow derivative with a planar, aromatic 18π‐electron perimeter, compound 1 was isolated. This interesting molecule has a strained, planar antiaromatic 12‐membered ring; dilute solutions of 1 are violet and resemble solutions of C 60 .
