In continuation of previous work, the behaviour of amino‐anthraquinones on fusion in pyridine ‐ aluminium chloride in the presence of oxidants is studied. Instead of dimerisation the reaction leads to salts of pyridinio‐aminoanthraquinones and further to condensed “anthraimidazopyridine” derivatives.
