Wang, Degui published the artcileFree radical induced oxidation of phloroglucinol. A pulse radiolysis and EPR study, Category: bromides-buliding-blocks, the main research area is radical induced oxidation phloroglucinol ESR; pulse radiolysis phloroglucinol.
Phloroglucinol (I)-derived radicals have been studied using pulse radiolysis and EPR spectroscopy. I (pKa = 8.0) and its anion (II) (pKa = 9.2) have phenolic structures while the 3,5-dihydrocyclohex-2,5-dienone structure predominates in the dianion (III). The neutral OH-adduct radicals (IIIa; λmax = 345 nm) rapidly eliminate water (k = 2 × 105 s-1) yielding the 3,5-dihydroxyphenoxyl radical (IV; λmax = 495 nm, pKa = 6.5). IV and its monoanion (V; λmax = 550 nm, pKa = 8.6), its isomer VI, derived from III (λmax > 800 nm), and the dianion (VII; λmax = 640 nm) can be generated directly with the N3 radical (k = 1.4 × 109 dm3 mol-1 s-1 at pH 6). All four radicals have been characterized by EPR. VI reacts with the phloroglucinol monoanion II with a rate constant of 2 × 107 dm3 mol-1 s-1. Formation of an adduct is excluded by EPR. Therefore, electron transfer from II to VI is favored as an explanation for this reaction. IV does not react with O2 (k < 4 × 105 dm3 mol-1 s-1); the anions V and VI do so quite rapidly (k = 2.1 × 108 and 1.9 × 108 dm3 mol-1 s-1, resp.) and at pH 7, O2 is consumed with G = 15 × 10-7 mol J-1. Although Br2•- mainly produces radicals IV and V, bromination occurs with an efficiency of at least 10%. Journal of the Chemical Society, Perkin Transactions 3: Physical Organic Chemistry published new progress about Autoxidation kinetics. 84743-77-1 belongs to class bromides-buliding-blocks, name is 2-Bromobenzene-1,3,5-triol, and the molecular formula is C6H5BrO3, Category: bromides-buliding-blocks.
