Abstract
AbstractThe high specificity of the reduction system zinc and ammonium salts in dimethyl methylphosphonate as solvent is demonstrated in several reductive dechlorination reactions of polychloropyridines. The reduction of pentachloropyridine with zinc/ammonium chloride system in dimethyl methylphosphonate yielded solely 2,3,5,6‐tetrachloropyridine. Similarly, the reduction of 2,3,4,5‐tetrachloropyridine with zinc and the tetramethylammonium salt of methyl methylphosphonate furnished exclusively 2,3,5‐trichloropyridine. A synthetic procedure for the preparation of the new ammonium salts of methyl methylphosphonate is given.
