Pyridazine and C-alkylpyridazines were found to yield N-ethoxycarbonyl-1,2-dihydropyridazines 1 - 6 when subjected to conditions of homolytic ethoxycarbonylation.This is the first example of an attack of a radical at the nitrogen atom of a N-heteroarene in Minisci-type reactions.
The Mechanisms of the Conversion of Thiophosphoryl Compounds into their Phosphoryl Analogues by Photochemically Excited 3-Methylpyridazine 2-Oxide and by 2-Methyl-3-p-nitrophenyloxaziridine; a Comparison

Reactions of tri-p-substituted triarylphosphine sulphides with 3-methylpyridazine 2-oxide, under photolysis, and with 2-methyl-3-p-nitrophenyloxaziridine both give the corresponding phosphine oxides.A detailed study and comparison of the two reactions shows that they are mechanistically quite distinct and that it is unlikely that the active oxygenating species generated by photolysis of the N-oxide, which attacks the phosphine sulphides, is an oxaziridine.The evidence presented suggests that this species may in fact be 'oxene'.
A STUDY ON THE TRANSITION STATE IN THE PHOTOOXYGENATIONS BY AROMATIC AMINE N-OXIDES

Oxygen-atom transfer process in the photolysis of aromatic amine N-oxides was suggested to involve the primary oxygen-atom elimination from N-oxides to give "oxene" followed by its reactions with the oxygen-acceptors.
