describe the eleven p-nitrobenzylazoles shown in Scheme 2 . Since those which were already known were insufficiently characterized, this paper will also report the complete assignment of their NMR (IH and 13C) spectra. An examination of the literature concerning p-nitrobenzylazoles shows that some of these compounds were synthesized for a study their photochemical behavior. Thus, Beugelmans et al. described
