Benzoyl chloride → Phenylglyoxylonitrile

Participants

Reaction Steps

72 g (0.5 mol) of sodium benzoate were mixed with 140.6 g (1 mol) of benzoyl chloride and 80 ml of tetramethylene-sulphone and 25 g (0.5 mol) of 98% pure sodium cyanide. After a stirring time of 20 minutes, an exothermic rise in the temperature to 85° C. was observed. It was now easier to stir the mixture. The subsequent reaction time was 2.5 hours at 150°-160° C. Working up gave the following yield: 65 g (99.3% of theory) of benzoyl cyanide; melting point 34° C.
