Synthesis of 1-naphthalenesulfonyl chloride

Preparation of 1-naphthalenesulfonyl chloride

40 g of sodium dry 1-naphthalene sulfonate are gradually added to an equal weight of coarsely powdered phosphorus pentachloride. The reaction takes place without heating, and the addition of the salt is so regulated that it does not become too violent. When the 1-naphthalene sulfonate has been added the reaction mixture is heated until it has become homogeneous. The phosphorus oxychloride removed by distillation under slightly reduced pressure (500 mm of Hg, 100° C). The crude 1-naphthalenesulfonyl chloride poured into a to ice-cold water, filtered and dried in vacuo. Purification is performed by recrystallization from a mixture of benzene and petroleum ether yielding colorless crystalline solid melting at 66° C. Yield of 1-naphthalenesulfonyl chloride is 60 %.
