Versuchsvorschrift

Trimethyl cyclohex-5-ene-1,2,4-tricarboxylate (200 mg, 0.78 mmol) is mixed with 305 mg of 5 percent by weight platinum on a carbon support in m-xylene (30 ml). The reaction mixture is refluxed with the reflux apparatus being open to air for 4 days. The residual platinum on carbon is then filtered off and the filtrate is concentrated down to a clear colorless gel. The desired product is obtained with a 65 percent yield. The yield is determined by GC/MS using a dodecane as an internal standard.
