Versuchsvorschrift

A mixture of 64.25 g of 4-chlorophenol, 98 g of anhydrous potassium carbonate, 40 g of chloroacetonitrile and 100 ml of dimethyl sulfoxide was heated with stirring in a 500 ml round-bottomed three-necked flask at 70°-80° C. for 3.0 hours. The reaction mixture was then poured into ice and water. After the ice melted, the mixture was filtered and the product washed well with water which gave 77.5 g of 4-chlorophenoxyacetonitrile.
