Versuchsvorschrift

A 70 mL stainless steel high pressure reactor having a Pyrex glass liner and a magnetic stir bar was charged with 5 mL of tetrahydrofuran, 0.5 mmol of n-pentadecane internal standard, 0.5 mmol of CH3OH, 4.88 mg of Fe(CO)5, and 57.19 mg of N-acetyl-2-pyrroline. The reactor was pressurized to 1000 psi with CO at room temperature, and the reaction mixture was stirred at 100° C. for 21 hours. Thereafter, the reactor was cooled to room temperature and vented to atmospheric pressure. The product mixture was analyzed by gas chromatography, and the analysis indicated 86.7% conversion of N-acetyl-2-pyrroline and 1.1% yield of N-acetylproline methyl ester.
