Versuchsvorschrift

2×10-2 moles of 2-methylthio-4-pentenenitrile are then dissolved in 50 ml of dry CH2Cl2. 2×10-2 moles of SO2Cl2 dissolved in 10 ml of CH2Cl2 are added dropwise. The mixture is stirred until gas evolution has ceased (silicone oil trap). The solvent is evaporated off and distillation is carried out at 82° C. at a pressure of 12 mm of mercury. 2-Chloro-2-methylthio-4-pentene-nitrile is obtained in a yield of over 95%.
