A new series of (benzofuran-2-yl)-1-phenyl-1H-pyrazol-4-yl) pyrimidine derivatives were synthesized from 3-(benzofuran-2-yl)-1-phenyl-1H-pyrazol-4-carbaldehyde (1) through different routes of cyclocondensation reactions. Condensation of 1 with active methylene compounds afforded compounds 2-8. The cyclization of 2 with chloroacetic acid, ortho substituted benzoic acid and/or ethanolamine gave c...

Type strains of the purple nonsulfur species Rhodospirillum rubrum, Rhodospirillum photometricum, and Rhodopseudomonas palustris grew phototrophically on a number of two- and three-carbon halocarboxylic acids in the presence of CO2, by reductive dehalogenation and assimilation of the resulting acid. Strains of each of these species were able to grow on chloroacetic, 2-bromopropionic, 2-chloropr...

We report the first halogen speciation analysis study by high performance liquid chromatography coupled with inductively plasma tandem mass spectrometry (HPLC-ICPMS/MS) in fruiting bodies of various mushroom species. Non-targeted revealed occurrence dichloroacetic acid (DCAA) edible Russula nigricans. Multiple samples this (n = 5) collected from different geographic non-industrial regions two c...

BACKGROUND Trichloroethene and tetrachloroethene are the most common pollutants in groundwater and two of the priority pollutants listed by the U.S. Environmental Protection Agency. In previous studies on TCE and PCE photolysis and photochemical degradation, concentration ranges exceeding environmental levels by far with millimolar concentrations of TCE and PCE have been used, and it is not cle...
