Abstract

In the photochemical and thermal decomposition of diazonium derivatives of 1-aryloxy- and 1-arylthio-2-aminoanthraquinones in CH 3 COOH and dioxane, high yields of intramolecular arylation products — anthra-[2, 1-d]-4-tert-butylbenzo-[b]-furan-and anthra-[2, 1-d]-4-tert-butylbenzo-[b]-thiophene-8,13-diones — are formed. It was established that 2-azo derivatives of 1-aryloxy- and 1-acyloxyanthraquinones synthesized on the basis of the diazonium salts are stable under photolysis conditions.
