Tighten your belt : [12]Cycloparaphenylene, the sidewall segment of a carbon nanotube (see picture), has been synthesized in a selective manner through stepwise palladium‐catalyzed coupling reactions. The synthesis capitalizes on the ability of the cis ‐1,4‐dihydroxycyclohexane‐1,4‐diyl unit to attenuate the build‐up of strain energy during macrocyclization.
