The Baeyer–Villiger oxidation is an organic reaction that forms an ester from a ketone or a lactone from a cyclic ketone, using peroxyacids or peroxides as the oxidant. [1] The reaction is named after Adolf von Baeyer and Victor Villiger who first reported the reaction in 1899.
General formulas of an organic peroxy acid (top) compared with a carboxylic acid (bottom).. A peroxy acid (often spelled as one word, peroxyacid, and sometimes called peracid) is an acid which contains an acidic −OOH group.
The general structure of an organic peroxide. In organic chemistry, organic peroxides are organic compounds containing the peroxide functional group (R−O−O−R′).If the R′ is hydrogen, the compounds are called hydroperoxides, which are discussed in that article.
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.
mcpb Other members of this group include 4-(2,4-dichlorophenoxy)butyric acid ( 2,4-DB ) and 4-(4-chloro-2-methylphenoxy)butyric acid ( MCPB ) which act as propesticides for 2,4-D and MCPA respectively: that is, they are converted in plants to these active ingredients. [ 4 ]
MCPB, 2,4-MCPB, 4-(4-chloro-o-tolyloxy)butyric acid (), or 4-(4-chloro-2-methylphenoxy)butanoic acid is a phenoxybutyric herbicide.In the United States it is registered for use on pea crops before flowering, for post-emergence control of broadleaf annual and perennial weeds including Canadian thistle, buttercup, mustard, purslane, ragweed, common lambsquarters, pigweed, smartweed, sowthistle ...
Structure of the acryloyl group. α,β-Unsaturated carbonyl compounds featuring a carbonyl conjugated to an alkene that is terminal, or vinylic, contain the acryloyl group (H 2 C=CH−C(=O)−); it is the acyl group derived from acrylic acid.
The frontier orbital interactions involved in the Prilezhaev reaction. The reaction proceeds through what is commonly known as the "butterfly mechanism", first proposed by Bartlett, wherein the peracid is intramolecularly hydrogen-bonded at the transition state. [5]
