- Study of the reaction of 2-acyl 1,3-dicarbonyl compounds with hydrazines by 1H NMR spectroscopy
-
The reaction of 2-acyl 1,3-dicarbonyl compounds with hydrazine and phenylhydrazine was studied by 1H NMR spectroscopy.It was shown that the formation of functionally 4-substituted pyrazoles is promoted if the reaction is conducted in protic solvents at reduced temperature.The presence of the benzoyl groups in the 2-acyl 1,3-dicarbonyl compounds leads to the preferential formation of the cleavage products, i.e., the corresponding acylhydrazines and 1,3-dicarbonyl compounds.It was established that the initial reaction product is consumed in two directions, i.e., cyclization with the formation of functionally 4-substituted pyyrazoles and cleavage with the formation of acetylhydrazines and the corresponding 1,3-dicarbonyl compounds.
