What are the products of reaction between acetone and meta chloro perbenzoic acid
Answers
Answer:
Peracids are general oxidants, usually with electrophilic properties (i.e. they react best with electron rich substrates). The reactivity of the peracid is determined by the electron wthdrawing character of the substituents. The stronger the parent acid, the more reactive the derived peracid. Thus trifluoroperacetic and 2,4-dinitroperbenzoic acids are stronger oxidants than peracetic and m-chloroperbenzoic (MCPBA) acids. Other peracid oxidants are based on persulfuric acid (oxone - KHSO5, and Caro's acid - H2SO5), percarbonic acid NaOOC(O)ONa) and perboric acid (sodium perborate).
Peracids that are not commercially available are prepared by the reaction of the acid chloride or anhydride with high-strength hydrogen peroxide or urea-hydrogen peroxide.
The vast majority of uses of percarboxylic acids involves three types of oxidations: alkenes to epoxides, Baeyer-Villiger oxidation of ketones to ester and lactones, and oxidation of heteroatoms to oxides (amines to amine oxides, sulfides to sulfoxides and sulfones, selenides to selenoxides, phosphine to phosphine oxides). Peracids do not easily oxidize alcohols, ethers, esters, amides or carboxylic acids. The most commonly used peracid is m-chloroperbenzoic acid (MCPBA) because it stores well and is commercially available. However, for more difficult oxidations (e.g. of electron-poor double bonds) more strongly electron deficient peracids such as trifluoroperacetic acid and dinitroperbenzoic acid are required.
