The electrochemical reduction of allyl chloride is strongly catalyzed in the presence of cobalt complexes of 2,2′‐bipyridine. A prominent reaction product of the catalyzed reduction is 1,5‐hexadiene. Voltammetry, coulometry, and gas chromatographic data are presented and analyzed and a mechanistic scheme proposed to account for the catalytic action of the cobalt‐2,2′‐bipyridine complexes
