Synthesis of Cycloparaphenyleneacetylene via Alkyne Metathesis: C70 Complexation and Copper-Free Triple Click Reaction.

Semin Lee1, Etienne Chénard1, Danielle L Gray1, Jeffrey S Moore1.   

Abstract

Alkyne metathesis provided an efficient macrocyclization route to a cycloparaphenyleneacetylene derivative in high yield. The cavity size was suitably matched for C70 which was tightly bound in an induced-fit fashion. The strained alkynes enabled a copper-free, 3-fold azide-alkyne cycloaddition at 50 °C.
