The reaction of N ‐(4‐dimethylaminophenyl)nitrones, 1 , with hydrogen azide proceeds via three distinct pathways to give a mixture of two tetrazoles, 5 and 9 , and a 2‐azido‐4‐dimethyl‐aminoaniline derivative, 6 . The proportions largely depend on the electron‐withdrawing force resident in the function R attached to nitrone carbon. The formation of 5 constitutes a new synthetic approach to 1,5‐disubstituted tetrazoles.
