30.4 g of 1-pentyl-4-(trans-4-pentylcyclohexyl)-cyclohexene [obtainable by reacting 4-(trans-4-pentylcyclohexyl)-cyclohexanone with pentyl-MgBr, hydrolysing the product to give 1-pentyl-4-(trans-4-pentylcyclohexyl)-cyclohexanol and dehydrating the latter], 2.7 g of liquid HCN, 0.1 g of palladium bis-[2,3-O-isopropylidene-2,3-dihydroxy-1,4-bis-(diphenylphosphino)-butane] and 100 ml of acetonitrile are heated at 130° for 1 hour in an autoclave. The mixture is cooled, evaporated and worked up in the customary manner to give r-1-cyano-1-pentyl-cis-4-(trans-4-pentylcyclohexyl)-cyclohexane, m.p. 28°, c.p. 63°.
