Kinetics and mechanism of oxidation of some meta- and para- substituted phenoxyacetic acids by N-chloropiperazine-2,5-dione in non-aqueous medium was written by Palaniappan, An.;Srinivasan, S.;Senthilkumar, S.. And the article was included in Asian Journal of Chemistry in 2002.Formula: C9H10O4 This article mentions the following:
The kinetics of oxidation of a number of meta- and para- substituted phenoxyacetic acids by N-chloropiperazine-2,5-dione (NCPD) were studied in methanol medium. The reaction shows unit order dependence with respect to oxidant and the order with respect to substrate varies depending on the nature of the substituent present in the ring. The rate is showing an inverse order of dependence with respect to [TsOH]. The rate increases with decrease in the percentage of methanol. Increase in ionic strength has no effect on the reaction rate. From the kinetic data obtained the activation parameters were computed and a suitable mechanism was proposed in accordance with multiparameter correlation anal. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Formula: C9H10O4).
2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Formula: C9H10O4
