资源简介：
A belt-shaped [8]cycloparaphenylene
(CPP) and an enantioenriched
Möbius-shaped [10]CPP have been synthesized by high-yielding
rhodium-catalyzed intramolecular cyclotrimerizations of a cyclic dodecayne
and a pentadecayne, respectively. This Möbius-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.
