meta-Chloroperoxybenzoic acid (mCPBA or mCPBA) is a peroxycarboxylic acid. It is a white solid often used widely as an oxidant in organic synthesis. mCPBA is often preferred to other peroxy acids because of its relative ease of handling. [1] mCPBA is a strong oxidizing agent that may cause fire upon contact with flammable material. [2]
Although many different peroxyacids are used for the Baeyer–Villiger oxidation, some of the more common oxidants include meta-chloroperbenzoic acid (mCPBA) and trifluoroperacetic acid (TFPAA). [2] The general trend is that higher reactivity is correlated with lower pK a (i.e.: stronger acidity) of the corresponding carboxylic acid (or alcohol ...
α-Phenylseleno aldehydes, which are usually prepared from the corresponding enol ethers, are usually oxidized with mCPBA or ozone, as hydrogen peroxide causes over-oxidation. α-Phenylseleno ketones can be prepared by kinetically controlled enolate formation and trapping with an electrophilic selanylating reagent such as benzeneselenyl chloride.
The epoxidation of allylic alcohols is a class of epoxidation reactions in organic chemistry.One implementation of this reaction is the Sharpless epoxidation.Early work showed that allylic alcohols give facial selectivity when using meta-chloroperoxybenzoic acid (m-CPBA) as an oxidant.
A widely used peroxy acid for this reaction is meta-chloroperoxybenzoic acid (m-CPBA), due to its stability and good solubility in most organic solvents. [1] [3] The reaction is performed in inert solvents (C 6 H 14, C 6 H 6, CH 2 Cl 2, CHCl 3, CCl 4) between -10 and 60 °C with the yield of 60-80%.
Imine are oxidized with meta-chloroperoxybenzoic acid (mCPBA) to give an oxaziridines. Imines are intermediates in the alkylation of amines with formic acid in the Eschweiler-Clarke reaction. A rearrangement in carbohydrate chemistry involving an imine is the Amadori rearrangement.

The general structure of a silyl enol ether. In organosilicon chemistry, silyl enol ethers are a class of organic compounds that share the common functional group R 3 Si−O−CR=CR 2, composed of an enolate (R 3 C−O−R) bonded to a silane (SiR 4) through its oxygen end and an ethene group (R 2 C=CR 2) as its carbon end.
