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]

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 ...
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.
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 ...
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.
