Pyridazine N-oxide Chemical Properties,Usage,Production

  • Uses Coupling partner in Pd-catalyzed direct arylation reactions.
  • Purification Methods Purify the oxide by distillation in a vacuum and by sublimation in vacuo. When a solution of the oxide in MeOH is treated with an aqueous solution of CuCl2, the [C4H4N2O]2—CuCl2-2H2O-complex (m 182-183o) is formed from which the oxide can be recovered . [Pollak et al.
