Ruthenium(III)-catalyzed oxidation of phenoxyacetic acids by aqueous phenyliodoso acetate was written by Gurumurthy, R.;Karunakaran, K.;Sathiyanarayanan, K.. And the article was included in Oxidation Communications in 1993.Formula: C9H10O4 This article mentions the following:
The kinetics of oxidation of phenoxyacetic acid and its derivatives (19 compounds) by phenyliodoso acetate has been studied in 60% (volume/volume) aqueous acetic acid. The reaction is first order with respect to both phenoxyacetic acid and phenyliodoso acetate and is catalyzed by hydrogen ions. Catalysis by Ru(III) is observed A Hammett ρ value of -2.62 at 35° indicates an electron-deficient transition state. The oxidation rates of ortho-substituted compounds have been analyzed by applying Taft’s steric energy parameters. A suitable mechanism has been proposed. 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. But on the other hand, ethers undergo cleavage by reaction with acids. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Formula: C9H10O4
