Igarashi, Mami published the artcileCatalytic oxidation of 2,4,6-tribromophenol using iron(III) complexes with imidazole, pyrazole, triazine and pyridine ligands, Recommanded Product: 1-Methylpyrazole, the publication is Journal of Molecular Catalysis A: Chemical (2016), 100-106, database is CAplus.
Five types of non-heme iron complexes, coordinated with imidazole, pyrazole, triazine and pyridine ligands, which had been previously synthesized, were used in the following studies. Among these complexes, the mer-[FeCl3(terpy)] complex showed the highest catalytic activity for the oxidative degradation of 2,4,6-tribromophenol (TrBP) using KHSO5 as an oxygen donor. The turnover numbers for the degradation and debromination of TrBP in the mer-[FeCl3(terpy)]/KHSO5 catalytic system were estimated to be 1890 ± 1 and 4020 ± 216, resp. The catalytic activity was significantly inhibited at pH 4-7 in the presence of a humic acid, a major component of landfill leachates. However, the percent of TrBP degradation and debromination increased at pH 8. GC/MS analyses showed that a major oxidation product was 2,6-dibromo-p-benzoquinone (DBQ) and its level decreased with increasing reaction time, suggesting that organic acids (identified by LC/TOF-MS) are formed via the ring-cleavage of DBQ. Mineralization to CO2 was observed to be 15% as a result of the oxidation for a 3 h period, where TOC values before and after the reaction were measured. Absorption spectra of mer-[FeCl3(terpy)] with m-chloroperoxybenzoic acids as an oxygen donor in acetonitrile showed that a center metal, Fe, formed a peroxide complex with the oxygen donor.
