Hexamethyl(Dewar benzene) was first obtained by bicyclotrimerization of 2‐butyne in the presence of aluminum chloride. This preparation provided a basis for a comprehensive study of the chemical reactivity of Dewar benzene derivatives. Interesting information concerning the reactivity of the permethylated Dewar benzene system can be deduced from its behavior on hydrogenation and oxidation, and, in particular, from the addition of H‐acidic compounds and from the substitution and elimination reactions of the resulting adducts.
