| | Pyridazine N-oxide Usage And Synthesis |
| 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.
