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]
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]
In organic chemistry, the acetoxy group (abbr. AcO or OAc; IUPAC name: acetyloxy [1]), is a functional group with the formula −OCOCH 3 and the structure −O−C(=O)−CH 3. As the -oxy suffix implies, it differs from the acetyl group (−C(=O)−CH 3) by the presence of an additional oxygen atom. The name acetoxy is the short form of acetyl-oxy.
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 ...

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 ...
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] Mg ...
