Sample text

For example, treatment of succinhydrazide with phosphoryl bromide yields 3,6-dibromopyridazine (Eq. 35) (182). H I H (35) Br 'Br Although they do not normally react-as ketone carbonyl groups, the 0x0 functions of both reduced and fully aromatic pyridazinones can be replaced by aromatic Grignard reagents. Reduced pyridazinones react by 1,2-addition, and apparently form diaryldihydropyridazines which dehydrogenate spontaneously. Only the fully aromatized products could be isolated (Eq. 36) (183-1 85).

In at least one case, a pyridazinone has been converted to its hydrazone. Thus 1 -methyl-6(1H)pyridazinone was treated with formylhydrazine and triethyloxonium fluoroborate to yield the 6-hydrazone (Eq. 38) (127). The hydrazone is reported to undergo oxidative coupling to yield azo dyes. Oximes 45 Reactions of several 4(1H)pyridazinones have also been reported (79), but these were formed by cyclization of the ring rather than replacement of the pyridazinone oxygen function. CHs CH3 B. Reactions of the Nucleus 1 , Electrophilic Substitution Pyridazinones do not undergo electrophilic substitution readily, but several instances of such reactions have been reported.
