Iodide reduction

WebReductions iodide Oxaziridines are powerful oxidizing agents. Free halogen is formed from hydrobromic acid (B-67MI50800). Reduction by iodide in acidic media generally yields a carbonyl compound, an amine and two equivalents of iodine from an oxaziridine (1).With 2-alkyl-, 2-acyl and with N-unsubstituted oxaziridines the reaction proceeds practically … Web8 sep. 2024 · Recently, methanogenic archaea, nitrate-reducing bacteria, iron-oxidizing bacteria, and iodide-oxidizing bacteria were also reported to corrode metallic iron (Fe 0) under anaerobic conditions. Clear understandings of the characterization of iron-corroding microorganisms are required for effective MIC prevention and control.
