Abstract An improved preparation of 1, 7-dimethylnaphthalene is presented, which is used as a precursor for the synthesis of diazoniahexacyclic salts, namely, 4a, 14a-diazoniaanthra [1, 2-a] anthracene (3) and 13a, 16a-diazoniahexaphene (7). The influence of the reaction conditions on the formation of these isomers was investigated. Notably, the selectivity of the reactions depends significantly on the acid employed in the cyclization step. Both ...
