Substituted Reaction Of Acyl Chlorine

ENERGYCO | Updated: Apr 03, 2018

When catalyzed by Lewis acid, such as ferric chloride or aluminum chloride, acyl chlorine can react with aromatic compounds (fu-G reaction) to produce aromatic ketone.

The mechanism of the reaction is: A similar reaction is the Nenitzescu reaction (or nenitshesku reaction), which is produced by the reaction of acyl chloride and olefin under the action of Lewis acid. The mechanism is that acyl cations first and the olefin occurred by the pro-electric addition to the formation of carbon positive ions, because the carbonyl alpha hydrogen is very lively, so the elimination of protons will get the unsaturated ketone.

Acyl chlorine and sodium peroxide produce benzoyl peroxide compounds, in the peroxide compound contains the peroxide bond-o-o-, under the heat or the illumination, the unstable peroxide acyl breaks down, releases the CO2 and produces the free radical, is the commonly used free radical reaction initiator. Benzoyl peroxide is a white crystalline powder with a melting point of 103-106 ℃. It is slightly soluble in water and has good solubility in ether, acetone, chloroform and benzene. The substance is flammable and can explode when struck, heated or rubbed, and reacts violently and burns when it meets with sulfuric acid. Benzoyl peroxide is used in rubber vulcanizing agent, oil refining, flour bleaching, fiber bleaching and so on.
