Polyesters with aromatic groups in the backbone from reactions of 3- and 4-bromomethylbenzoic acids with triethylamine was written by Pinkus, A. G.;Subramanyam, Ravi;Hariharan, Rajan. And the article was included in Journal of Macromolecular Science, Pure and Applied Chemistry in 1992.COA of Formula: C8H7BrO2 This article mentions the following:
Aromatic polyesters were obtained in yields ∼70% from reactions of 3- and 4-bromomethylbenzoic acids with triethylamine in PhCl. A copolymer was prepared in 58% yield by reaction of a 1:1 mixture of the 2 acids under similar conditions. The polyesters were characterized by IR, 1H- and 13C-NMR spectra, x-ray powder diffraction, DSC behavior, solution viscosity, and hydrolysis to the corresponding hydroxymethylbenzoic acids. Mol. weights were determined by 1H-NMR end group anal. Possible mechanisms for the reactions were discussed. In the experiment, the researchers used many compounds, for example, 3-(Bromomethyl)benzoic acid (cas: 6515-58-8COA of Formula: C8H7BrO2).
3-(Bromomethyl)benzoic acid (cas: 6515-58-8) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.COA of Formula: C8H7BrO2
