| Abstract: | The electron transfer reaction of Cr(VI) with organic sulfides is facilitated by added pyridine bases 2,2′-bipyridine, 1,10-phenanthroline,
picolinic acid and pyridine 2,6-dicarboxylic acid. The added base forms a Cr(VI)-base adduct carrying positive charge which
acts as a more reactive oxidant compared to Cr(VI). UV–Visible spectrophotometric study provides evidence for the formation
of Cr(V) as the intermediate. The reactions in the absence and presence of pyridine bases follow the reactivity–selectivity
principle. |
