Abstract

Action of chlorine in the presence of iron on molten 4-nitrobenzo-2, 1, 3-thiadiazole gives mainly 4, 5, 6, 7-tetrachlorobenzo-2, 1, 3-thiadiazole, with a little 4, 7-dichlorobenzo-2, 1, 3-thiadiazole(VI). The tetrachloro compound is also found by the action of chlorine in the presence of iron on 4-nitro-5-chlorobenzo-2, 1, 3-thiadiazole. The action of chlorine in the presence of iron on 5-nitrobenzo-2, 1, 3-thiadiazole gives 5-nitro-7-chlorobenzo-2, 1, 3-thiadiazole. The structures of the reaction products are proved by retrosynthesis and thin-layer chromatography.
