  6. Alkyne trimerisation - Wikipedia

    en.wikipedia.org/wiki/Alkyne_trimerisation

    An alkyne trimerisation is a [2+2+2] cycloaddition reaction in which three alkyne units (C≡C) react to form a benzene ring. The reaction requires a metal catalyst. The process is of historic interest as well as being applicable to organic synthesis. [1] Being a cycloaddition reaction, it has high atom economy.
