Pyridazine N-oxide Chemical Properties,Usage,Production

Uses

Coupling partner in Pd-catalyzed direct arylation reactions.

Synthesis

Pyridazine N-oxide was prepared as follows: appropriate diazine (1 eq.) and mCPBA (1 eq.) were dissolved in DCM (0.2 M). The reaction was stirred for 16 hours. PPh3 (0.5 eq.) was then added to reduce any unreacted peracid and the mixture was stirred for a further 4 hours. The volatiles were evaporated under reduced pressure and the residue was purified by silica gel column chromatography to give pyridazine N-oxide.

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.
