実験手順

When the thallous salts of ethyl acetoacetate, 2 -carbethoxycyclopentanone, and 3-methylpentane-2,4-dione, prepared according to Example 1, are treated with acetyl fluoride at room temperature as described in Example 4, ethyl 2-acetylacetoacetate, 2-acetyl-2-carbethoxycyclopentanone, and 3-acetyl-3-methylpentane-2,4-dione, respectively, are obtained in 95% yield. Tribenzoylmethane is prepared by treating the thallous salt of dibenzoylmethane with benzoyl fluoride in the same manner. Acetyldibenzoylmethane is prepared by treating the thallous salt of dibenzoylmethane with acetyl fluoride.
