To a stirred suspension of dry sodium acetylacetonate (1.83g, 15mmol) in 20 ml CH₃CN at 0deg.C freshly prepared bis(5-methylfur-2-yl)methylperchlorate [1] (2.74g, 10mmol) was added in small portions waiting for decolouration between each one. After further stirring for 15 min, the mixture was poured into 100 ml of H₂O. Extraction with Et₂O, drying of the ether layer by Na₂SO₄ and evaporation gave the brown oil, which was dissolved in acetone, filtered through a pad of silica gel and then left to crystallize. Yield 1.53g (56%).

M.p. 59-60deg.C.
