The anhydrous material and dihydrate Mn(CH 3 CO 2) 2 ·2H 2 O are coordination polymers. The dihydrate has been characterized by X-ray crystallography. Each Mn(II) center is surrounded by six oxygen centers provided by aquo ligands and acetates. Subunit of the structure of the dihydrate of manganese(II) acetate. [5]

Manganese triacetate has been used as a one-electron oxidant.It can oxidize alkenes via addition of acetic acid to form lactones. [3]This process is thought to proceed via the formation of a •CH 2 CO 2 H radical intermediate, which then reacts with the alkene, followed by additional oxidation steps and finally ring closure. [1]

[7] 2 CH 3 COOH + Mg(OH) 2 → (CH 3 COO) 2 Mg + 2 H 2 O. Magnesium carbonate suspended in distilled water with 20% acetic acid solution. [8] 2 CH 3 COOH + MgCO 3 → Mg(CH 3 COO) 2 + CO 2 + H 2 O. Reacting metallic magnesium with acetic acid dissolved in dry benzene causes magnesium acetate to form along with the release of hydrogen gas. [9 ...
The equilibrium, between the gas as a separate phase and the gas in solution, will by Le Châtelier's principle shift to favour the gas going into solution as the temperature is decreased (decreasing the temperature increases the solubility of a gas). When a saturated solution of a gas is heated, gas comes out of the solution.
Cu 2 (OAc) 4 + 2 RC≡CH → 2 CuOAc + RC≡C−C≡CR + 2 HOAc. The reaction proceeds via the intermediacy of copper(I) acetylides, which are then oxidized by the copper(II) acetate, releasing the acetylide radical. A related reaction involving copper acetylides is the synthesis of ynamines, terminal alkynes with amine groups using Cu 2 (OAc ...
When Cu(OAc) 2 is present, further oxidation to carbocations followed by elimination takes place, leading to the formation of β,γ-unsaturated carbonyl compounds in moderate yields. [9] (4) Aromatic compounds are also useful radical acceptors in manganese(III)-mediated coupling reactions.
