Abstract
Alkyne metathesis is a powerful method for synthesizing alkyne-containing molecules under thermodynamic control. Alkyne metathesis has been effective in preparing natural products and various organic materials such as shape-persistent macrocycles, cages, polymers, and covalent organic frameworks. Here, various Mo(VI)-alkylidyne-based catalysts with multidentate ligands will be explored. Additionally, a scalable preparation method for carbon nanohoops using alkyne metathesis will be presented. Strain-promoted reactions and polymerization of carbon nanohoops will also be discussed.
