Tribromoacetic acid

Tribromoacetic acid [75-96-7] (Br CCOOH), mol wt 296.74, C2HBr302, mp 135°C bp 245°C (decomposition), is soluble in water, ethyl alcohol, and diethyl ether. This acid is relatively unstable to hydrolytic conditions and can be decomposed to bromoform in boiling water. Tribromoacetic acid can be prepared by the oxidation of bromal [115-17-3] or perbromoethene [79-28-7] with fuming nitric acid and by treating an aqueous solution of malonic acid with bromine. [Pg.90]

The phenomenon of halotropism occurs in the reaction of tribromoacetic, 2-bromopropanoic and fnm -3,4-dibromocyclopentane-l-carboxylic acid with sulfur tetrafluoride. Tribromoacetic acid reacts at 25 C to give l,l,2-tribromo-l,2,2-trifluoroethane (6a) in 95% yield, while the other two acids give mixtures of trifluoromethyl derivatives 7 and rearranged 1,1,2-tri-fluoroalkanes6.110 The halogen shifts confirm the carbocationic mechanism of the fluorination reaction (vide supra). [Pg.350]

Trichloroacetic acid, upon treatment with sulfur tctrafluoride/hydrogen fluoride, yields the expected l,l,l-trichloro-2,2.2-trifluorocthane whereas tribromoacetic acid rearranges to... [Pg.194]

The haloacetic acids (HAA) are comprised of mono-, di- and trichloroacetic acid, mono-, di-, and tribromoacetic acid, and bromo-chloroacetic acid, bromo-dichloroacetic acid, and dibromo-chloroacetic acid. Toxicological studies showed that these compounds have carcinogenic properties and may have adverse reproductive consequences. HAA have no strong chromophore for sensitive UV detection electrochemical detection has been described. Analysis by GC-MS requires derivatization. Due to their relatively low molecular mass, the LC-MS analysis can be hindered by low-mass background interferences. [Pg.225]

The decarboxylation affords dibromoacetic acid, but in the presence of bromine the end-product is tribromoacetic acid since bromine has no effect on the rate of reaction, and since dibromoacetic acid is not brominated under the reaction conditions, the carbanion mechanism is conclusively proved for this case. [Pg.1010]
