Versuchsvorschrift

1-Cyano-2-(2,2-dichlorovinyl)-3,3-dimethylcyclopropanecarboxylic acid (1.5 g) was dissolved in dimethylformamide (10 ml) and the solution was saturated with gaseous ammonia at 20° C. The solution was then stirred at 130° C. for 18 hours, then diluted with water (150 ml) and extracted with pentane. The extracts were dried (MgSO4) and the solvent was removed under reduced pressure to give the required 2-(2,2-dichlorovinyl)-3,3-dimethylcyclopropane nitrile, yield 82%.
