Manganese(II) acetate are chemical compounds with the formula Mn(CH 3 CO 2) 2 ·(H 2 O)n where n = 0, 2, 4. These materials are white or pale pink solids.
Although manganese(III) triacetate has not been reported, salts of basic manganese(III) acetate are well characterized. Basic manganese acetate adopts the structure reminiscent of those of basic chromium acetate and basic iron acetate. The formula is [Mn 3 O(O 2 CCH 3) 6 L n]X where L is a ligand and X is an anion. The salt [Mn 3 O(O 2 CCH 3) 6 ...

Mn(acac) 3 has been prepared by the comproportionation of the manganese(II) compound Mn(acac) 2 with potassium permanganate in the presence of additional acetylacetone. [12] Alternatively the direct reaction of acetylacetone with potassium permanganate. [13] In terms of electronic structure, Mn(acac) 3 is high spin.
Manganese-mediated coupling reactions are radical coupling reactions between enolizable carbonyl compounds and unsaturated compounds initiated by a manganese(III) salt, typically manganese(III) acetate. Copper(II) acetate is sometimes used as a co-oxidant to assist in the oxidation of intermediate radicals to carbocations.
Chromium(II) acetate, Cr 2 (μ-O 2 CCH 3) 4 (H 2 O) 2, was the first chemical compound containing a quadruple bond to be synthesized. It was described in 1844 by E. Peligot, although its distinctive bonding was not recognized for more than a century.
Manganese has no satisfactory substitute in these applications in metallurgy. [53] Steelmaking, [74] including its ironmaking component, has accounted for most manganese demand, presently in the range of 85% to 90% of the total demand. [61] Manganese is a key component of low-cost stainless steel.
Jacobsen's catalyst is the common name for N,N'-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminomanganese(III) chloride, a coordination compound of manganese and a salen-type ligand. It is used as an asymmetric catalyst in the Jacobsen epoxidation , which is renowned for its ability to enantioselectively transform prochiral alkenes ...
