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]
(4) Aromatic compounds are also useful radical acceptors in manganese(III)-mediated coupling reactions. Furan reacts selectively at the α position to afford substituted products in high yield. [10] (5) Lactonization of alkenes in the presence of acetic acid and acetate salts is a synthetically useful method for the synthesis of γ-lactones.
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]

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 ...
CH 3 COOH + 2H + + 2e − → CH 3 CHO + H 2 O: −0.58 Many carboxylic acid: aldehyde redox reactions have a potential near this value 2 H + + 2 e − → H 2: −0.41 Non-zero value for the hydrogen potential because at pH = 7, [H +] = 10 −7 M and not 1 M as in the standard hydrogen electrode (SHE), and that: E red = -0.059 V × 7 = -0.41 V ...
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.
