Reaktionsschritte

6-Bromonaphth-2-ylsulphonyl chloride (9.4 g) was added in small portions over 3 hours to a stirred mixture of sodium sulphite heptahydrate (14.46 g), sodium bicarbonate (5.08 g) and water (100 ml) which had been heated to 70° C. The resultant mixture was allowed to cool slowly to ambient temperature. The crystalline precipitate was isolated giving sodium 6-bromonaphth-2-ylsulphinate (8.07 g) which was used without further purification.
