Amino-N-oxides

Nitropyridazines are reduced catalytically either over platinum, Raney nickel or palladium-charcoal catalyst. When an N-oxide function is present, palladium-charcoal in neutral solution is used in order to obtain the corresponding amino N-oxide. On the other hand, when hydrogenation is carried out in aqueous or alcoholic hydrochloric acid and palladium-charcoal or Raney nickel are used for the reduction of the nitro group, deoxygenation of the N- oxide takes place simultaneously. Halonitropyridazines and their N- oxides are reduced, dehalogenated and deoxygenated to aminopyridazines or to aminopyridazine N- oxides under analogous conditions. 

Amino groups in pyridazine N- oxides can be diazotized and the diazonium group further replaced by halogens, hydroxy group or hydrogen. So, 3-, 4-, 5- and 6-bromopyridazine 1-oxides can be prepared from the corresponding amino N- oxides.
