| | Dimedone Usage And Synthesis |
| Chemical Properties | solid | | Uses | Part of furannulation strategy for the synthesis of naturally occurring fused 3-methylfurans.1 | | Uses | A mentha compound showing antimicrobial properties against common bacteria in the food industry such as E.coli and P.aeruginosa as well as strains of yeast. | | Uses | Used in the synthesis of fused 3-methylfurans via furannulation. | | Uses | Reagent used in synthesis of fused 3-methylfuransDimedone is used in organic chemistry to identify the presence of aldehyde group. It is also used as a catalyst in the formation of transition-metal complexes. Further, it is also employed in colorimetry, crystallography, luminescence and spectrophotometric analysis. In addition to this, it is used in the synthesis of naturally occurring fused 3-methylfurans. | | Synthesis Reference(s) | Journal of the American Chemical Society, 77, p. 6656, 1955 DOI: 10.1021/ja01629a086
Organic Syntheses, Coll. Vol. 2, p. 200, 1943 | | General Description | 5,5-dimethyl-1,3-cyclohexanedione (Dimedone) is basically a highly sensitive and very specific reagent used for the determination of aldehydes. It is highly advantageous as it is environment friendly, give high yields and is a simple workup procedure. | | Purification Methods | Crystallise dimedone from acetone (ca 8mL/g), water or aqueous EtOH. Dry it in air. [Schneider & Todd Org Synth Coll Vol II 200 1943, Beilstein 7 H 559, 7 IV 1999.] |
