Dechlorination of pyridines in acidic, zinc-containing mediums
Described are preferred processes for preparing 3,5-dichloropyridines by dechlorinating higher-chlorinated pyridine compounds such as 2,3,5,6-tetrachloropyridine in an acidic medium in the presence of zinc and optionally a quaternary ammonium catalyst.
