Reaction of pseudonitroles and their derivatives with diaminofurazan in the presence of dibromoisocyanuric acid (DBI) resulted in symmetrical 3,4-bis(-nitroalkyl-ONN-azoxy)-furazans or their derivatives. For the synthesis of bis(nitroalkyl-ONN-azoxy)furazans bearing various a-nitroalkyl-ONN-azoxy groups, the method based on the reaction of α-nitronitroso compounds with 3-amino-4-(nitroalkyl)-ONN-azoxy)furazans (in the presence of DBI) was developed. Synthetic procedures towards aforementioned compounds with nitromethyl-, dibromonitromethyl-, trinitromethyl-ONN-azoxy and other groups were described.
