2-Alkynyl-l-amino-9,10-anthraquinones react with HNO2 in a mixture of dilute HCl and dioxane at 20 °C to give I , 1-dichloroalkyl- IH-3-naphto[2,3-g]indazole-6,1 1 -diones. This reaction differs from the known cyсlization of ortho-alkynylbenzenediazonium salts involving the formation of a pyridazine ring (the Richter synthesis of 4-hydroxy- and 4-halocinnolines).
