Abstract By the reaction of 2-chloro-3-alkyl-, 2,3-dichloro(dibromo)-, trichloro-(tribromo)-and tetrachloro(tetrabromo)-naphthazarins and 2,3-dichloroquinizarin with Fe/HOAc followed by oxidation with an air in a mild basic conditions the corresponding naphthazarins and quinizarin were obtained in good to excellent yields.
