Abstract

The ^13^C NMR spectra of 1,5‐ and 2,x‐dinitroindazoles “x=4‐7” and 3‐bromo‐1,x‐dinitroindazoles are recorded and discussed. The data on he 2,x‐dinitroindazoles confirm our previous structurea assignment based on ^1^H NMR spectroscopy. The ^13^C NMR spectra established that in the novel 3‐bromo‐1,x‐dinitroindazoles the N‐nitro group is attached at N‐1.
