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 acetate itself can effect the second oxidation of resonance-stabilized adduct radicals to carbocations 5; [5] unstabilized radicals undergo further transformations before reacting with Mn(OAc) 3. Atom transfer from another molecule of substrate may generate saturated compound 3. Adduct radicals or carbocations may undergo ligand ...
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 ...
In the Eglinton reaction Cu 2 (OAc) 4 is used to couple terminal alkynes to give a 1,3-diyne: [13] [14] 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 ...
Enthalpy change of solution in water at 25 °C for some selected compounds [2] Compound ΔH o in kJ/mol; hydrochloric acid: −74.84 ammonium nitrate +25.69 ammonia: −30.50 potassium hydroxide: −57.61 caesium hydroxide: −71.55 sodium chloride +3.87 potassium chlorate +41.38 acetic acid: −1.51 sodium hydroxide: −44.50
The compound can be prepared by treating nickel or nickel(II) carbonate with acetic acid: . NiCO 3 + 2 CH 3 CO 2 H + 3 H 2 O → Ni(CH 3 CO 2) 2 ·4 H 2 O + CO 2. The mint-green tetrahydrate has been shown by X-ray crystallography to adopt an octahedral structure, the central nickel centre being coordinated by four water molecules and two acetate ligands. [5]
