Synthesis of N-β-haloethyl derivatives of bis(oxytriazene oxides) bearing the NCH2O fragment

Resumo

Synthetic procedures towards 3-monosubstituted functional derivatives of 1-alkoxy-1-triazene 2-oxides were elaborated. Alkylation of the synthesized compounds with chloromethoxy derivatives of 3,3-bis(2-haloethyl)-1-hydroxy-1-triazene 2-oxides gave (2-chloro/ bromoethyl) derivatives of 1,2,3,6,7,8-hexaaza-5-oxa-3-alkoxyocta-1,6-diene 2,7-dioxides. 2-Iodoethyl-1,2,3,6,7,8-hexaaza-5-oxa-3-alkoxyocta-1,6-diene 2,7-dioxides were first synthesized by the reaction of the corresponding bromoethyl derivatives with NaI.
