Mechanosynthesis of Odd‐Numbered Tetraaryl[n]cumulenes

A mechanochemical synthesis of one‐dimensional carbon allotrope carbyne model compounds, namely tetraaryl[n]cumulenes (n=3, 5) was realized. Central for the mechanosynthesis of the cumulenic carbon nanostructures were the development of a mechanochemical Favorskii alkynylation‐type reaction and the...

Summary:A mechanochemical synthesis of one‐dimensional carbon allotrope carbyne model compounds, namely tetraaryl[n]cumulenes (n=3, 5) was realized. Central for the mechanosynthesis of the cumulenic carbon nanostructures were the development of a mechanochemical Favorskii alkynylation‐type reaction and the implementation of a solvent‐free, acid‐free reductive elimination with tin(II) chloride by ball milling. Eindimensionale Mechanochemie: Ein mechanochemischer Ansatz wurde entwickelt, der einen Zugang zu Tetraaryl[n]cumulenen eröffnet. Hierdurch werden die Anwendungen der Mechanochemie auf eindimensionale Kohlenstoffnanostrukturen erweitert.
