Similarly to 3-chloro-3-(dimethylamino)acrolein (2), 5-chloro-5-(dimethylamino)penta-2,4-dienal (6) easily rearranges in the presence of traces of acid to 2-(dimethylamino)pyrilium chloride (8), which is the postulated intermediate of the rearrangement of 6 to 5-chloropenta-2,4-dien-N,N-dimethylamide (10).
