Спосіб отримання
Compounds of this family are prepared by condensation of substituted benzyl cyanides with the corresponding cycloalkanones. A mixture of cyclohexanone and 2-methyl benzylcyanide is treated with potassium hydroxide and heated to 120 °C (oil bath 140 °C) for 2 hours, while water distils off as an azeotrope with cyclohexanone. The crude product crystallises on standing and is subjected to a short path distillation at 0.05 mbar. The distillate is recrystallised three times from hexane, which gives a white crystalline product in 50% yield.

У парфумерії
In a fragrance, replacing 100 parts of Peonile by cyclohexylidene-o-tolyl-acetonitrile enhances the floral rosy aspect, adds notes of exotic fruits such as lychee and makes the composition much more elegant. The compounds of this family may be used alone or in combination with known odorant molecules.
