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]
Values from CRC refer to "100 kPa (1 bar or 0.987 standard atmospheres)". Lange indirectly defines the values to be standard atmosphere of "1 atm (101325 Pa)", although citing the same NBS and JANAF sources among others.
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 ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The outcomes of manganese-mediated coupling reactions depend on both the structure of the substrate(s) and the reaction conditions. This section describes the scope and limitations of inter- and intramolecular manganese-mediated radical coupling reactions and is organized according to the carbonyl compound employed as the substrate.
