3-(2,4-Dimethoxyphenyl)acrylic acid (cas: 6972-61-8) 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. 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).Recommanded Product: 3-(2,4-Dimethoxyphenyl)acrylic acid

Carbon-13 NMR studies on reaction mechanisms. IV. Solvolysis of 4-aryl-n-butyl brosylates was written by Fujio, Mizue;Taguchi, Miyako;Wada, Yoshiko;Seki, Yoji;Mishima, Masaaki;Tsuno, Yuho. And the article was included in Memoirs of the Faculty of Science, Kyushu University, Series C: Chemistry in 1980.Recommanded Product: 3-(2,4-Dimethoxyphenyl)acrylic acid This article mentions the following:

The solvolysis of methoxy-substituted 4-phenylbutyl-1–13C (90% enriched) brosylate gave both open-chain ester products and isomeric products (e.g., 6- or 7-methoxytetralin-1–13C) via anchimerically-assisted pathways. The 13C NMR tracer technique was applied to the solvolysis mechanism and kinetics. Suitably positioned MeO groups accelerated the anchimerically assisted route. Transition states for the assisted pathways were discussed. In the experiment, the researchers used many compounds, for example, 3-(2,4-Dimethoxyphenyl)acrylic acid (cas: 6972-61-8Recommanded Product: 3-(2,4-Dimethoxyphenyl)acrylic acid).
