Reaction Conditions:
in water for 0.25 h;Heating / reflux;
Steps:
13 EXAMPLE 13manganese (1H) acetylacetonate, Mn(acac)⊆3⊃ or Mn(C⊆5⊃H⊆7⊃O⊆2⊃)⊆3⊃
Powdered KMnO4 (5.0 g, 31.7 mmol) was dissolved in minimum amount of water by slight warming over a stem bath and the solution then filtered. Distilled acetylacetone (22.0 mL, 220 mmol) was added to the solution with continuous stirring. A white crystalline compound was precipitated. The whole mixture was stirred for 15 min over steam bath and then allowed to cool for 10 min. Dark brown shiny crystals of Mn(acac)3 was filtered and finally dried in vacuo over fused CaCl2. Yield: 9.7 g (87%). The compound does not have sharp melting point but decomposes at ca.155° C. (dec.). IR and Mass Spectra of the compound match well with those reported in literature. Analytical data: The compound analyzed correctly C15H21MnO6. Calc. M, 352: C, 51.15: H, 6.00: Mn, 15.6% Found. M (mass spectrum), 352: C, 51.1: H, 6.10: Mn, 15.7%
