Versuchsvorschrift
A mixture of 2-nitrobenzoyl chloride (500 mg) with 4-trimethylsilanyloxy-pent-3-en-2-one (540 mg) was stirred at 140° C. for 5 min. The reaction solution was cooled to room temperature and was then purified by column chromatography using acetone-hexane to give 3-(2-nitro-benzoyl)-pentane-2,4-dione (143 mg, yield 20%).
