1 Source of material
All reagents were obtained from commercial sources and used without further purification. 3-methyl-1-p-tolyl-5-pyrazolone was synthesized according to the method proposed by Jensen (1959) (yield 78.6 %; m.p. 402–403 K). 3–methyl-1-p-tolyl-5-pyrazolone (5 g) was dissolved in dioxane (100 mL) by warming and Ca(OH)2 (3 g), added. 2-Furoyl 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 2 M HCl (450 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 crystallisation occurred. Filtration of the product gave 76 % yield of light yellow crystals at room temperature.
2 Experimental details
The hydroxyl H atom was located in a difference Fourier map and refined as riding, with O–H distance restraint of 0.82(1) A° and with Uiso(H) = 1.5 Ueq(O). Other H atoms were placed in calculated positions, with C–H = 0.93 for phenyl and furan, and refined as riding, with Uiso(H) = 1.2 Ueq(C) for phenyl H and 1.5 Ueq(C) for methyl H.
3 Comment
The 4-heterocyclic acylpyrazolones are an interesting class of β-diketones, containing a pyrazole-bearing chelating arm [5]. Such 4-heterocyclic acylpyrazolones derivatives were found to be useful as NMR shift-reagents [6], and it is also important in understanding the behavior of these compounds in the vapor phase, the mechanisms of pharmacological activities and physiological activities [7]. Moreover, they can coordinate with metal to generate complexes [8, 9]. Although there have been numerous reports on acylpyrazolones, few 4-heterocyclic acylpyrazolone compounds have been reported so far [10, 11].
The structure of the title compound is shown in figure. The p-tolylphenyl ring is slightly twisted by 6.23(6)° with respect to the pyrazolone ring, whereas the furyl rings make dihedral angles of 4.40(5)° with the pyrazolone. Atom O1 has a partial anionic character, as shown by the lengthening of the C8=O1 bond [1.293(3) Å] and this atom acts as hydrogen-bond acceptor. The intermolecular O1–H1⋯O2 hydrogen bond results in the formation of a dimer with an R22(12) graph-set motif [12]. It is apparent that the C12=O2 and C9=C12 distances correspond to double bonds. The conjugation effects also cause the pyrazolone and C2–C7 benzene ring to be nearly coplanar, with a mean deviation from the overall plane of 0.002 Å. Atoms O1, C8, C9, C12 and O2 are essentially coplanar, the largest deviation from the mean plane being 0.009 Å for C12. 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 geometric parameters are in the expected ranges [14].
