Kinetics and mechanism of chlorination of phenoxyacetic acids by N-chloro-3-methyl-2,6-diphenylpiperidin-4-one was written by Kabilan, S.;Sankar, P.;Krishnasamy, K.. And the article was included in Oxidation Communications in 1994.Category: ethers-buliding-blocks This article mentions the following:
Chlorination of phenoxyacetic acid and several of its meta- and para-substituted derivatives by N-chloro-3-methyl-2,6-diphenylpiperidin-4-one yields monochlorinated product through a direct rate limiting attack at the ortho-carbon. The reaction is first order with respect to [substrate] and [oxidant]. Increase in [H+] and [Cl–] increases the rate of reaction. The reaction rate does not show any significant change with an increase in ethanol content of the medium. The reaction is inhibited by added piperidone. The mechanistic pathways of the reaction have been discussed and substantiated through multiparameter correlation anal. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Category: ethers-buliding-blocks).
2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Category: ethers-buliding-blocks
