Sulfochlorination of 1,2-Naphthoquinone-(2)-diazide by Chlorosulfonic acid.The sulfochlorination of 1,2-naphthoquinone diazide-(2) (1) by chlorosulfonic acid was investigated. The yields of the formed products (1,2-naphthoquinone diazide-(2)-4-sulfonic acid (4), 1,2-naphthoquinone diazide-(2)-5-sulfonic acid (5), 1,2-naphthoquinone diazide-(2)-4-sulfochloride (2) and 1,2-naphthoquinone diazide-(2)-5-sulfochloride (3)) depend on the temperature and on the time of reaction. The highest yields of the favoured 1,2-naphthoquinone diazide-(2)-4-sulfochloride (2) are obtained at 63°C and after a reaction time of 80 minutes (50%).
