Notes:
4H,5H-Benzo[1,2-c;3,4-c′]bis[1,2,5]thiadiazole-4,5-dione (2) was prepared by oxidation of 4-bromobenzobis[1,2,5]thiadiazole (3d) with nitric acid and subsequently converted into 5,6-dihydroxybenzenetetramine dihydrochloride (10) and the dimethoxy derivative 13. Treatment of the 4-hydroxy derivative 3a with chromium(VI) reagents led to cleavage of the benzene ring, giving dicarboxylic acid 4.
