Procedure: 159.1 g (1.5 mols) of the sodium salt of acetylcyanamide and 137.8 g (1.5 mols+20% excess) of allyl chloride are reacted in 400 ml of sulfolane for 9 hours and 45 minutes at 70°-127° C. analogously to Example 1, and the mixture is worked up in accordance with Example 1. This gives 121.7 g (65.4% of theory) of a colourless distillate, boiling at 98° C./43 mbar.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 23.3 g (0.2 mol+10% excess) of the sodium salt of acetylcyanamide and 30.5 g (0.2 mol) of vinylbenzyl chloride (technical mixture of isomers containing approx. 40% of the para-component and 60% of the meta-component) are reacted in 100 ml of dimethylformamide for 8 hours at 48°-50° C., when the reaction is complete the mixture is filtered with suction, the filtrate is introduced into 300 g of ice and 500 ml of water while stirring vigorously and the mixture is then extracted with ethyl acetate. The ethyl acetate solution is dried with anhydrous sodium sulfate and filtered with suction, the filtrate is decolourised with active charcoal, the solution is filtered and the filtrate is concentrated in vacuo at 40° C. on a rotary evaporator. The residue is dried to constant weight at 40° C./0.13 mbar. This gives 34.9 g (87.1% of theory) of a brownish, viscous liquid, which is purified by bulb tube distillation at 130°-145° C./0.7 mbar. containing approx. 40% of the para-component and 60% of the meta-component) is filtered with suction the filtrate is introduced into 300 g of ice and 500 ml of water the mixture is then extracted with ethyl acetate The ethyl acetate solution is dried with anhydrous sodium sulfate filtered with suction the solution is filtered the filtrate is concentrated in vacuo at 40° C. on a rotary evaporator The residue is dried to constant weight at 40° C./0.13 mbar This gives 34.9 g (87.1% of theory) of a brownish, viscous liquid, which is purified by bulb tube distillation at 130°-145° C./0.7 mbar
