Reaction Conditions

Temperature20 °C

Reaction Steps

30.4 g (0.2 mole) of o-cyanobenzyl chloride are dissolved in 70 g of dimethylformamide, and 24 g (0.6 mole) of sodium hydroxide powder are added at the same time as nitrogen is passed in. The mixture is stirred at 20° C. for about 6-10 hours until all the organically bound chlorine has reacted, 70 g of methanol are added dropwise, and the precipitate is filtered off with suction at 0° C. and is washed with methanol and then with water until no chlorine ions are detectable in the water from the wash. Drying gives 17.8 g of stilbene-2,2'-dicarbonitrile in the form of white crystals.
