sulfoxide one. The reason for such behavior is the hydrogen
bond existing between a couple of HOF molecules and the
weak complexation between them and acetonitrile.19 Thus, two
HOF molecules approach the sulfur atom of a sulfide, or as in
our case to a nitrogen atom, but only in pyridazines is the
second reagent molecule near the second nitrogen atom, and a
simultaneous attack takes place on both heteroatoms to form
the corresponding N,N-dioxide (option A in Scheme 7). This

mechanism was supported by an experiment where MeOH was
deliberately added to the reaction mixture, thus breaking the
hydrogen bonds between the reagent molecules and creating
new ones with the methanol. The result was a quantitative
formation of pyridazine mono-oxide 11 independent of the
concentration of the reagent and the reaction times (option B
in Scheme 7). The distance between the heteroatoms in the
pyrimidine series does not allow a complexation with a pair of
the reagent molecules, resulting in mono-oxidation only
(Scheme 6).
This simultaneous attack of both nucleophilic nitrogens on
the receptive nearby oxygens is responsible for the fact that 3-
chloropyridazine (38) forms only the mono-oxide 3920
(Scheme 5, last entry). Although chlorine is a less powerful
electron-withdrawing group than the cyan in 27, the yield of the
dioxide is practically 0%. The chlorine atom is bulkier than the
linear CN, interfering with the second molecule of the HOF
dimer to attack simultaneously the additional nitrogen situated
near the chlorine atom.

In conclusion, for many decades, it was practically impossible
to oxidize the two nitrogen atoms of one of the simplest
heterocycle systems, the pyridazine family. Elemental fluorine,
through one of its offspring reagents, HOF·CH3CN, succeeded
where all other oxygen-transfer agents have failed. We believe
that this dioxide may find many uses in the near future
including serving as a new ligand in many studies.21
