Microwave-assisted O-alkylation of carboxylic acids in dry media: Expeditious synthesis of 2-Oxo-2-arylethyl carboxylates was written by Li, Z.;Quan, Z. J.;Wang, X. C.. And the article was included in Chemical Papers in 2004.Reference of 1877-75-4 This article mentions the following:
Microwave-assisted O-alkylation reactions of carboxylic acids, such as aryloxyacetic acids, 4-chlorobenzoic acid, (un)substituted furoic acids, and benzofuroic acid, with (un)substituted ω-haloacetophenones in dry media under phase-transfer catalysis are described. 2-Oxo-2-arylethyl carboxylates are expeditiously synthesized by this method in high yield using Bu4NBr as catalyst. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Reference of 1877-75-4).
2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. At room temperature, ethers are pleasant-smelling colourless liquids.
