A simple route to 2-aryl-substituted naphtho[2,1-e][1,2,4]triazinium and naphtho[2,1-e][1,2,3,4]tetrazinium salts from 1-arylazo-substituted 2-naphthylamines

1-Arylazo-substituted 2-naphthylamines, which are easily obtainable by the coupling of arene diazonium salts with 2-aminonaphthalene-sulfonic acid, can be transformed by reaction with reactive carboxylic acid derivatives or nitrosation reagents into novel 2-aryl-substituted naphtho[2,1-e][1,2,4]triazinium and naphtho[2,1-e][1,2,3,4]tetrazinium salts, respectively.
