Abstract
A process for preparing pyridine derivatives, particularly dipyridyls which are intermediates for the production of herbicides and photographic and metal treatment chemicals, comprises passing an electrical discharge, preferably a silent electrical discharge of the type used in ozoniser equipment, through pyridine or pyridine derivatives in the liquid or vapour state in the absence of oxygen or oxygen-containing compounds.
