1 Source of material

All reagents were obtained from commercial sources and used without further purification. 1-(4-chlorophenyl)-3-methyl-1H-pyrazol-5(4H)-one was synthesized according to the method proposed by Jensen (1959) (yield 84.5 %; m.p. 441–443 K). 1-(4-chlorophenyl)-3-methyl-1H-pyrazol-5(4H)-one (5 g) was dissolved in dioxane (100 mL) by warming and Ca(OH)2 (3 g), added. Benzoyl chloride (5 mL) was next added, drop by drop, with stirring within 3 min. After refluxing gently for 1 h, the orange mixture was cooled and poured with stirring into chilled 3 M HCl (300 mL). A handful of ice-salt mixture was added and vigorous stirring continued for another 30 min, after which, the reaction mixture was kept in a refrigerator until crystallization occurred. Filtration of the product gave 85 % yield of light yellow crystals.

2 Experimental details

The hydroxyl H atom was located in a difference Fourier map. Other H atoms were placed in calculated positions, with C—H = 0.93 for phenyl and furan, and refined as riding, with Uiso(H) = 1.2Ueq(C) for phenyl H.

3 Comment

Acylpyrazolones are an interesting class of β-diketones, containing a pyrazole-bearing chelating arm [6]. Thus, they can coordinate with a variety of metal elements to generate complexes with different structures [7, 8]. A few years ago, we have synthesized heterocyclic acylpyrazolone ligands substituted by chlorine at the position 1 and studied their crystal structures [9, 10]. In order to expand this field, we use the methyl and benzoyl substituents at the 3- and 4-positions in the formation of the title compounds.

The structure of the title compound is shown in the Figure. Atom O1 shows the lengthening of the C7=O1 bond [1.296(3) Å] relative to that normally found for carbonyl groups and this atom acts as hydrogen-bond acceptor. The intermolecular O—H⋯O hydrogen bond results in the formation of a dimer with an R22(12) graph-set motif [12]. It is apparent that the C11=O2 and C8=C11 distances correspond to well defined double bonds. The conjugation effects also cause the pyrazolone and C1–C6 benzene ring to be nearly coplanar, with a mean deviation from the overall plane of 0.010 Å. Atoms O1, C7, C8, C11 and O2 are essentially coplanar, the largest deviation from the mean plane being 0.044 Å for C11. The dihedral angle between the C1–C6 benzene ring and the pyrazolone ring is 18.56(2)°. The clear presence of the hydroxyl H atom in the difference Fourier synthesis and the absence of any residual electronic density in the vicinity of O1 confirm that the title compound crystallizes as a pure hydroxyl tautomer and that no desmotropism is present [13]. All bond lengths and angles are normal and comparable with those found for related compounds [11, 14, 15].
