P. Cailleux et al., CYCLOADDITION OF METHYLAZIDE AND PHENYLAZ IDE WITH BETA-NITROSTYRENE AND HOMOLOGOUS NITROPROPENE, Bulletin des Societes chimiques belges, 105(1), 1996, pp. 45-51
Phenylazide and emthylazide reacts with title olefines and gives two i
someric triazoles without nitro group, and 4-nitro-1,2,3 triazole. The
isomerisation of starting alkenes explains the formation of isomeric
triazoles. Oxydation of amino-nitro-diazocompounds in equilibrium with
1,2,3 triazolines leads to 4-nitro-1,2,3 triazoles.
