2,4-dimethoxybenzoic acid and 2,5-dimethoxybenzoic acid.
Barich DH, Zell MT, Powell DR, Munson EJ. Barich DH, et al. Acta Crystallogr C. 2004 Apr;60(Pt 4):o261-2. doi: 10.1107/S0108270104003063. Epub 2004 Mar 20. Acta Crystallogr C. 2004. PMID: 15071229
The title compounds (both C(9)H(10)O(4)) have nearly planar structures, and the methyl and/or carboxylic acid groups lie out of the molecular plane, as dictated by steric interactions. 2,5-Dimethoxybenzoic acid (2,5-DMBA) forms an unusual intramolecula …

How Acid-Catalyzed Decarboxylation of 2,4-Dimethoxybenzoic Acid Avoids Formation of Protonated CO2.
Howe GW, Vandersteen AA, Kluger R. Howe GW, et al. J Am Chem Soc. 2016 Jun 22;138(24):7568-73. doi: 10.1021/jacs.6b01770. Epub 2016 Jun 13. J Am Chem Soc. 2016. PMID: 27241436
The decarboxylation of 2,4-dimethoxybenzoic acid (1) is accelerated in acidic solutions. ...However, this would produce the conjugate acid of CO2, a species that would be too energetic to form. Considerations of mechanisms that fit the observed …

Carbon Kinetic Isotope Effects and the Mechanisms of Acid-Catalyzed Decarboxylation of 2,4-Dimethoxybenzoic Acid and CO(2) Incorporation into 1,3-Dimethoxybenzene.
Vandersteen AA, Howe GW, Sherwood Lollar B, Kluger R. Vandersteen AA, et al. J Am Chem Soc. 2017 Oct 25;139(42):15049-15053. doi: 10.1021/jacs.7b07504. Epub 2017 Oct 13. J Am Chem Soc. 2017. PMID: 28982238
The rate of decarboxylation of 2,4-dimethoxybenzoic acid (1) is accelerated in parallel to the extent that the carboxyl group acquires a second proton (1H(+)). However, the conjugate acid would resist C-C bond breaking as that would lead to form …
