Versuchsvorschrift

A three-neck flask is equipped with mechanical stirrer, reflux condenser and dropping funnel. The flask is charged under N2, with 42 ml of a 1.0 M solution of lithium aluminum hydride in anhydrous ether (42 mmol). A solution of 5 g of 5-Norbornene-2-carbonitrile (bicyclo[2.2.1]hept-5-ene-2-carbonitrile) in 45 ml of ether (42 mmol, 1.0 M) is added dropwise through the addition funnel at a rate that allows a gentle reflux. After one hour, the mixture is cooled to 0° C. and water is added dropwise until hydrogen gas liberation is no longer observed. To this, 100 ml of 20% sodium potassium tartrate is added and produces a clear solution. The reaction solution is transferred to a separatory funnel, and the aqueous phase is collected and washed with 3×50 ml portions of ether. The combined ether fractions are dried with calcium sulfate and solvent is removed by rotary evaporation yielding a yellow oil. This product is further distilled under reduced pressure to yield a clear oil.
