title = "Synthesis of Belt- And M{\"o}bius-Shaped Cycloparaphenylenes by Rhodium-Catalyzed Alkyne Cyclotrimerization",
abstract = "A belt-shaped [8]cycloparaphenylene (CPP) and an enantioenriched M{\"o}bius-shaped [10]CPP have been synthesized by high-yielding rhodium-catalyzed intramolecular cyclotrimerizations of a cyclic dodecayne and a pentadecayne, respectively. This M{\"o}bius-shaped [10]CPP possesses stable chirality and isolated with high enantiomeric purity. It is evident from the reaction Gibbs energy calculation that the above irreversible cyclotrimerizations are highly exothermic; therefore establishing that the intramolecular alkyne cyclotrimerization is a powerful route to strained cyclic molecular strips.",
