Reaction Steps
A mixture of 19.3 g. (0.1 mol) o-(1-cyclohexenyl)-chlorobenzene and 16.4 g. (0.18 mol) cuprous cyanide in 100 ml. N-methylpyrrolidinone was heated to 200° C. for 15 hours. For working up, the brown-black product was introduced into a solution of 40 g. ferric chloride, 10 ml. concentrated hydrochloric acid and 60 ml. water and the mixture heated for 0.5 hours to 60° to 70° C. The N-methylpyrrolidinone phase was separated off and the aqueous phase was extracted several times with toluene. The combined organic phases were successively washed with 2N hydrochloric acid, water and 10% aqueous sodium hydroxide solution and subsequently dried with anhydrous sodium sulphate and evaporated. Fractional distillation gave the desired benzonitrile derivative. Yield 68% of theory; b.p. 90-92° C./0.1 mm.Hg; nD26 =1.5648.
