Safety of 5-Chloro-1-methyl-4-nitroimidazole. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Chloro-1-methyl-4-nitroimidazole, is researched, Molecular C4H4ClN3O2, CAS is 4897-25-0, about Electrochemical reduction of bifunctional organic compounds. XI. Substituted N-methylnitroimidazoles. Author is Kargin, Yu. M.; Latypova, V. Z.; Fassakhov, R. Kh.; Arkhipov, A. I.; Eneikina, T. A.; Sharnin, G. P..
The mechanism was studied of the electrochem. reduction of nitro- and halo-substituted N-methylimidazoles where the substituents are NO2, Cl, Br, H, and NHPh. The process begins with the reverse transfer of an electron to the mol. to form anion radicals with different degrees of stability. The rate of anionic elimination of Br- from positions 2 and 5 in the anion radicals of 1-methyl-2(5)-bromo-4-nitroimidazole (k = 8.2 ± 0.5 and 12.1 ± 0.5 s-1, resp.) was evaluated.
