抄録

Condensation of nitrobenzylideneacetylacetone (Ia, b), which have double bond on 3 position of acetylacetone, with hydrazine dihydrochloride in several alcoholic solvents afforded 3, 5-dimethyl-4-nitrobenzylideneisopyrazolium alkyl chlorides. On the other hand, reaction of Ia, b with hydrazine dihydrochloride in acetonitrile gave 3, 5-dimethyl-4-nitrobenzylideneisopyrazole (IIa, b). These structures and chemical natures were examined.
