| Product | Benzenesulfonyl chloride, 4-chloro-3-nitro- | HCID 7323 | 82.1% |
Reaction Steps
157.6 g (1.0 mol) of 2-chloronitrobenzene and 699 g (6.0 mol) of chlorosulfonic acid are reacted as in Example 22, but without addition of sulfamic acid. 212.8 g of 2-nitrochlorobenzene-4-sulfonyl chloride having a water content of 1.2%, corresponding to 210.2 g of 2-nitrochlorobenzene-4-sulfonyl chloride (82.1% of theory), are obtained.
