However, in a nonaqueous solvent, the hydrolysis is prevented and the epoxide ring can be isolated as the product. Then, the oxygen is inserted on top. References 19,21, Vollhardt, Peter, and Neil E. Draw the intermediate of this reaction. Jorge A. For more explanation of how this reaction leads to vicinal diols, see below. This reaction was performed under photochemical irradiation [23,24]but weak selectivity and low isolated yields were observed.
Magnesium monoperoxyphthalate (MMPP) is a water-soluble peroxy acid used as an oxidant in organic synthesis.
Its main areas of use are the conversion of. Magnesium Monoperoxyphthalate Hexahydrate, MMPP • 6 H2O.
Recent Literature. A series of α-diketones were readily prepared by the.
Oxacyclopropane synthesis by peroxycarboxylic acid requires an alkene and a ion bound to magnesium, which gives magnesium monoperoxyphthalate (MMPP ). In either case.

This procedure has considerable advantages over the previously reported oxidation methods, because no other positions of the molecule are oxidized concomitantly, it avoids the use of halogenated solvents, and allows easy recovery of the reaction products.

A cyclic osmic ester is formed. A syn-1,2-ethanediol is formed. Proton transfer from the acid catalyst generates the conjugate acid of the epoxide, which is attacked by nucleophiles such as water in the same way that the cyclic bromonium ion described above undergoes reaction.

More recently, magnesium monoperoxyphthalate (MMPP) was introduced as a safer substitute less prone to thermal decomposition. Many other peracids are.

This hydration of an epoxide does not change the oxidation state of any atoms or groups. References 45, One way the epoxide ring can be opened is by an acid catalyzed oxidation-hydrolysis. Meso-3,4-hexanediol is formed.
