    The Scholl reaction is a Lewis acid‐catalyzed coupling of aromatic compounds while eliminating two of the aryl‐bound hydrogens and is generally known as Scholl condensation. Occasionally, this reaction is also referred to as the Scholl oxidation. This study finds that the use of molten SbCl3,and anhydrous HF facilitate the formation of a Scholl condensation product. This reaction is useful in the production of polycyclic aromatic hydrocarbons and carbon nanotube segments.

    In the arenium ion mechanism one reaction partner is protonated to an arenium ion which then attacks the second reaction partner. The arenium ion can also be formed by attack of the Lewis acid. The mechanisms are difficult to distinguish because many Lewis acids can behave as oxidants.

    The Scholl reaction is a coupling reaction between two arene compounds with the aid of a Lewis acid and a protic acid. It is named after its discoverer, Roland Scholl, a Swiss chemist. ... The protic acid in the Scholl reaction is often an impurity in the Lewis Acid and also formed in the course of a Scholl reaction.
