Coupling partner in Pd-catalyzed direct arylation reactions.
What are the applications of Application
Pyridazine N-oxide is A 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.
