Comment top

Epoxy resins have the combination of good thermal and dimensional stability, excellent chemical and corrosion resistance, high tensile strength and modulus, and ease of handling and processability, ensuring their wide application in the aerospace and electronic industries in the form of structural adhesives, advanced composite matrices, and packaging materials (Dušek, 1985). The properties of cured epoxy polymers largely depend on the nature of the chemical structure of the starting resins and curing agents. The title compound (I) is a precursor in an attempt to synthesize imidazole derivatives and transition metal complexes as epoxy resin curing agents and accelerators. Substituted thioureas are an important class of compounds, precursors or intermediates towards the synthesis of a variety of heterocyclic systems such as imidazole-2-thiones (Zeng et al., 2003), 2-imino-1, 3-thiazolines (D'hooghe et al., 2005), pyrimidine-2-thiones and (benzothiazolyl)-4-quinazolinones. Thioureas are also known to exhibit a wide range of biological activities including antiviral, antibacterial, antifungal, antitubercular, antithyroidal, herbicidal and insecticidal activities (Huebner et al., 1953) and as agrochemicals (Xu.Y et al., 2004). One example are 1-benzoyl-3-(4,5-disubstituted-pyrimidine-2-yl) thioureas, which have excellent herbicidal activity (W.Zheng et al., 2004). Thioureas are also well known chelating agents for transition metals (Xue et al.,2003). N,N-Dialkyl-N'-benzoyl thioureas act as selective complexing agents for the enrichment of platinum metals even from strongly interfacing matrixes.The complexes of thiourea derivatives also show various biological activities (Glasser et al., 1964). Thioureas and substituted thioureas are also known as epoxy resin curing agents. We became interested in the synthesis of N-Aroyl, N'-arylthioureas as intermediates towards some new novel heterocycles and for the systematic study of their bioactive complexes and epoxy resin curing agents. In this article, we describe the spectroscopy and crystal structure of ethyl 4-(3-benzoylthioureido)-benzoate (I) as a typical representative of N-aroyl, N'-arylthioureas. Compound (I) crystallizes in the thioamide form. The conformation of the molecule with respect to the carbonyl and thiocarbonyl part is essentially planar, as reflected by the torsional angles O1—C7—N1—C8, C7—N1—C8—S and C7—N1—C8—N2 of 0.7 (2), -177.97 (9) and 1.0 (2) °, respectively. However, there is rotation about the various moieties as indicated by e.g. C6—C1—C7—N1 34.7 (2) and C8—N2—C9—C14 136.9 (1) °. Apart from the atoms O1, N1, C8 and S, the molecule is planar (mean deviation of non-H atoms is 0.055 Å). The C7—O1, C8—S and C15—O2 bonds show a typical double bond character with bond lengths of 1.226 (1), 1.659 (1) and 1.215 (1) Å, respectively. All of the C—N bonds, C9—N2 1.415 (1), C7—N1 1.385 (1), C8—N2 1.339 (2), and C8—N1 1.401 (1) Å also indicate partial double bond character. Among the three latter C—N bonds, C7—N1 is the longest, indicating an C(sp2)—N(sp2) single bond, while C8—N2 is the shortest bond with more double bond character. This demonstrates that there is π conjugation in the system S—C8—N2 but not along O1—C7—N1 and C7—N1—C8, as found in 1-(3-methoxybenzoyl)-3,3-diethylthiourea (Moraless et al., 2000).

There is a strong intramolecular hydrogen bond N2—H02···O1, with distances H2···O1 1.89 (2) and N2···O1 2.618 (1) Å, resulting in a 6-membered ring. Molecules are connected in chains parallel to [101] by the classical H bond N1—H01···O2; weak C—H···S interactions are observed interconecting the chains (Table 1).

Experimental top

The title compound was synthesized by a slight modification of the published procedure (Douglas et al., 1934). A solution of benzoyl chloride (0.1 mol) in anhydrous acetone (70 ml) was added dropwise to a suspension of ammonium thiocyanate (0.1 mol) in anhydrous acetone (50 ml) and the reaction mixture was refluxed for 45 minutes. After cooling to room temperature, a solution of p-aminobenzoic acid ethyl ester (0.1 mol) in anhydrous acetone (25 ml) was added and the resulting mixture refluxed for 1.5 hrs. The reaction mixture was poured into five times its volume of cold water where the thiourea precipitated as a solid. The product was recrystallized from ethyl acetate as pale yellow crystals (3.55 g, 85%). m.p. 425 K. Elemental analysis for C17H16N2O3S (M=328.38) calc.

Refinement top

H atoms of NH groups were refined freely. Methyl H atoms were included on the basis of idealized rigid groups (C—H 0.98 Å, H—C—H 109.5°) allowed to rotate but not tip. Other hydrogen atoms were included using a riding model with C—H 0.95 (aromatic) or 0.99 (methylene) Å. U(H) values were fixed at 1.5Uiso(C) of the parent C atom for methyl H, 1.2Uiso(C) for other H.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
