Reaction Conditions

Reaction Steps

At 10° to 15° C., 13 g of potassium cyanide is dissolved in 100 ml of glacial acetic acid. At 10° C., a solution of 61.4 g of 2-trichloromethyl-4-nitrobenzenesulfenic acid chloride in 200 ml of diethyl ether is added to the solution. The mixture is stirred for 2 hours at 10° C. and for 5 hours at room temperature. The precipitated potassium chloride is filtred off, the solvent is distilled off, and the residue is recyrstallized from petroleum ether. There is obtained 53 g (89% of theory) of 2-trichloromethyl-4-nitrophenyl thiocyanate; m.p.: 72° C.
