Electrocatalytic production of 2,3,5,6-tetrachloropyridine from pentachloropyridine

摘要

2,3,5,6-Tetrachloropyridine is obtained in high selectivity and yield by the electrocatalytic reduction at a stainless steel cathode of pentachloropyridine in an aqueous acetonitrile solution containing zinc chloride. Chlorine or oxygen may be co-produced at the anode.
