Procedure

3.3 g of 1,2-dichloro-2-cyano-vinyl 2-chloro-2-cyano-vinyl sulphide were dissolved in 20 ml of methylene chloride, 2 g of potassium carbonate were added, and 2.15 g of sulphuryl chloride in 10 ml of dichloroethane were added dropwise at room temperature. The mixture was stirred at 70° C. for 12 hours and filtered, the filtrate was washed with water and concentrated and the resulting oil was chromatographed. 1.7 g of bis-(1,2-dichloro-2-cyano-vinyl) sulphide were obtained as an oil, which was identical to the product from Example 8.
