Abstract
Aryldiazonium salts couple with the 3-dimethylamino-1-substituted enon es 1 a-c to yield 2-arylhydrazono-3-oxo-3-substituted-propanals which are excellent precursors for the synthesis of pyridazinones. The coupl ing reaction of dimethylamino-3-substituted-penta-2,4-dienonitrile 12 a-b with benzene diazonium salts in ethanolic sodium hydroxide gives t he pyridazinals 13a,b.
