Structural characterization of benzoyl-1H-pyrazole derivatives obtained in lemon juice medium: Experimental and theoretical approach

Simple, one-pot, and low-cost reactions of acetylacetone with a variety of substituted benzoyl hydrazides in lemon juice, as eco-friendly medium, were performed. In reactions of benzoyl hydrazides with electron-donating groups on phenyl ring, the 1-benzoy

TAUTOMERISM IN THE SERIES OF ACYLHYDRAZONES OF ACETYLACETONE AND α-ALKYLATED β-DIKETONES

It was shown by PMR spectroscopy that acetylacetone acylhydrazones exist in the 5-hydroxypyrazoline form in the crystalline state and in solutions in deuterochlorofom and in the form of an equilibrium mixture of the enehydrazine and 5-hydroxypyrazoline fo

TAUTOMERISM IN THE SERIES OF BENZOYLHYDRAZONES OF ALIPHATIC β-DICARBONYL COMPOUNDS

It was shown by PMR spectroscopy that the benzoylhydrazones of aliphatic β-dicarbonyl compounds exist in solutions as tautomeric mixtures of the cyclic 5-hydroxypyrazoline and open forms.The latter are represented by the hydrazone or enehydrazine form or their combination, depending on the structure of the β-dicarbonyl component and the solvent.Increase in the size of the terminal substituent at the C=N bond displaces the equilibrium toward the cyclic 5-hydroxypyrazoline form, and the introduction of strong electron-withdrawing substituents at the C=N bond favors the hydrazone and cyclic forms.The benzoylhydrazones of symmetrical β-diketones have a cyclic 5-hydroxypyrazoline structure.

REACTIONS OF β-DIKETONES WITH ACYLHYDRAZINES

The reaction of acetylacetone with the hydrazides of aliphatic and aromatic acids was investigated.By IR and PMR spectroscopy it was shown that the products from condensation of acetylacetone with acylhydrazines exist at 1-acyl-3,5-dimethyl-5-hydroxypyraz
