“…Moreover, benzofuran-93 and benzothiophene-condensed derivatives 94 of 9,10-anthracenedione were obtained by the photocyclization of 1-aryloxy(arylthio)-9,10-dioxoanthracenyldiazonium chlorides 91 and 92 in dioxane or in a mixture of acetate acid with dioxane [39].…”

For the first time, the literature sources concerning the chemical transformations of diazonium salts of 1(2)-amino-9,10-anthracenediones are generalized and systematized. The potential of 9,10-dioxoanthracenyldiazonium salts as key substrates in the preparation of various linear-functionalized, acyclic and heterocyclic derivatives has been determined. The main synthetic transformations of diazonium salts of amino-9,10-anthracenediones, which are realized without preserving the azo function lead to the formation of reaction products of Sandmeyer, Meerwein, and Gomberg–Bachmann–Hay, are analyzed. The use of 9,10-dioxoanthracenyldiazonium salts or products of their transformations for obtaining heteryl-containing condensed and functionalized derivatives is presented.
