A copper-catalyzed cascade dehydrogenative and dehalogenative reaction of halogenated 6-phenyl-4,5-dihydropyridazin-3(2H)-ones to 6-phenylpyridazin-3(2H)- ones has been developed. Moreover, the catalytic system consisting of copper(II) acetate/sodium carbonate/pyridine exhibits high reactivity and selectivity with oxygen as the terminal oxidant. Copyright

Irrespective of the nature of the substituents at positions 1 and 3 the heterocycle, 6-oxo-1-phenyl(methyl)-3-aryl-1,6-dihydropyridazines are alkylated by the action of triethyloxonium fluoroborate at the oxygen atom of the carbonyl group, forming heteroaromatic 1-ethoxypyridazinium salts.
