Twenty‐four N ‐benzyliaeneanilines (four being new compounds) have been prepared, which are divided conveniently into three series: (I) with 4‐substituents, plus one compound with 3‐ and 4‐substituents; (II) with 4′‐substituents, plus one compound with 3′‐ and 4′‐substituents; and (III) with 4‐ and 4′‐substituents. Their 13 C NMR spectra and the 1 H NMR absorption of the hydrogen attached to the imidoyl carbon atom have been studied and their Hammett correlations were tested.
