ABSTRACT The reactions of chlorination of the pyridine compounds are conducted by means of molecular chlorine, with the use, as free-radical forming initiator, of a decachloro butane or an octachlorobutene such as octachlorobutene-1 or a crude mixture of these chlorine-containing products obtained by additive chlorination of hexachlorobutadiene-1,3. Good rates of conversion are obtained, and good yields at moderate temperatures. The method is applied, for example, to the chlorination of pyridine and beta-picoline.
