Irradiation of pyridine N-oxide (1) in the presence of secondary amines in aqueous solution produces mixtures of isomric 2Z,4E and N,N-disubstituted all-E 5-amino-2,4-pentadienenitriles (3 and 4), in fair yields, and with an ease to render the reaction preparatively useful.Furthermore, such compounds can be prepared thermally by dehydration of 5-amino-2,4-pentadienal oximes.
