Suschitzky, H.; Chivers, G. E. published the artcile< Polyhaloaromatic compounds. XXI. Novel reagent system for the N-oxidation of weakly basic N-heteroaromatic compounds>, Safety of 2,3,4,6-Tetrachloropyridine, the main research area is pyridine oxidation pyridine oxide preparation; pyridazine oxidation pyridazine oxide preparation; pyrazine oxidation pyrazine oxide preparation; substitution nucleophilic pyridine.
By use of H2O2-H2SO4-AcOH or-CF3CO2H, pentachloro-, 2,3,4,6-tetrachloro-, 2,6-dichloro-, tetrachloro-4-nitro-, and pentabromopyridine, and tetrachloropyridazine and -pyrazine were oxidized to their N-oxides in >50% yields. 3,5-Dichloro-2,4,6-trifluoropyridine was oxidized by H2O2-polyphosphoric acid to give 3,5-dichloro-2,4-difluoro-6-hydroxypyridine 1-oxide; pentachloropyridine reacted with AcOH-H2SO4 to give 2,3,4,5-tetrachloro-6-hydroxypyridine by nucleophilic substitution.
Journal of the Chemical Society [Section] C: Organic published new progress about Oxidation. 14121-36-9 belongs to class pyridine-derivatives, and the molecular formula is C5HCl4N, Safety of 2,3,4,6-Tetrachloropyridine.
