The cover picture shows the deflagration of 20 mg of hexaspiro‐[2.4.2.4.2.4.2.4.2.4.2.4]dotetraconta‐4,6,11,13,18,20,25,27,32,34,39,41‐dodecayne—truly an exploding [6]rotane—and the chair‐shaped structure of its 30‐membered ring with six 1,3‐butadiyne and six spirocyclopropane units. The compound is obtained in 39% yield from the oxidative coupling of two open‐chain halves and decomposes spontanteously upon heating or impact. The picture was put together electronically from a videotape of the explosion and a representation of the crystal structure (fototeam Hansjürgen Gutzeit GmbH, Göttingen (FRG)). A. de. Meijere et al. report on this and related molecules on p. 869 ff.
