## Abstract ^13^C‐ and ^15^N‐NMR. spectra have been measured for a series of triazenes. The results are compatible with the significant contribution of a structure such as II. One‐bond nitrogen‐nitrogen coupling constants are reported.
## Abstract __cis__‐ and __trans__‐2‐imino‐1,3‐ and ‐3,1‐perhydrobenzoxazines and the __N__‐methyl derivatives of the latter were synthesized from the corresponding cyclic 1,3‐amino alcohol with cyanogen bromide. The configurations of the studied compounds were confirmed by ^1^H and ^13^C NMR spect
