A mixture of 5,5-dimethyl-3-phenylamino-2-thioxo-4-imidazolidione (0.71 g, 3 mmol), hexyl bromide (0.50 g, 3 mmol) and solid potassium carbonate (0.83 g, 6 mmol) in CH3CN (15 ml) was stirred for 5 h at 323 K and was filtered. The filtrate was condensed, and the residue was recrystallized from diethyl ether and petroleum ether (1:3) to give the title compound (I) in yield of 83% (m.p. 355 K). Suitable crystals were obtained by slow evaporation of a solution of (I) in dichloromethane and petroleum ether at room temperature.
All H atoms were located in difference maps and treated as riding atoms, except those at N1, with the following distance restraints: C—H = 0.93 Å, Uiso = 1.2Ueq(C) for Csp2, C—H = 0.97 Å, Uiso = 1.2Ueq(C) for CH2, N—H = 0.86 Å, Uiso = 1.2Ueq(N) for NH2, C—H = 0.96 Å, Uiso = 1.5Ueq(C) for CH3.
Imidazolinones are important heterocycles exhibiting remarkable biological activities, especially fungicidal activities (Khodair et al., 1998). Since a novel mitochondrial respiratory inhibitor (Fenamidone) was found to show high fungicidal activities, many other 2-alkylthio imidazolinones have been synthesized to evaluate their fungicidal activities (Bruhn et al., 1998). We obtained the title compound, (I), which may be used as a new precursor for obtaining bioactive molecules. The crystal structure of (I) is presented here.
Atom S1, N1 and the five-membered imidazolone ring are essentially planar. The C16 and C17 atoms, and the hydrogen atoms attached to C15, C16 and C17 are disordered over two sites, with refined occupancies of 0.309 (7) and 0.691 (7) (Fig. 1). The bond lengths involving atom C9 indicate a degree of electron delocalization (Yuan et al., 2006). As can be seen from the packing diagram (Fig. 2), intermolecular N—H···N and C—H···O hydrogen bondings (Table 1) link the molecules.
Imidazolinones have been prepared and their biological activities, especially their fungicidal activities, have been studied by Khodair et al. (1998) and Bruhn et al. (1998). For related literature, see: Yuan et al., 2006.

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. |

Imidazolinones are important heterocycles exhibiting remarkable biological activities, especially fungicidal activities (Khodair et al., 1998). Since a novel mitochondrial respiratory inhibitor (Fenamidone) was found to show high fungicidal activities, many other 2-alkylthio imidazolinones have been synthesized to evaluate their fungicidal activities (Bruhn et al., 1998). We obtained the title compound, (I), which may be used as a new precursor for obtaining bioactive molecules. The crystal structure of (I) is presented here.
Atom S1, N1 and the five-membered imidazolone ring are essentially planar. The C16 and C17 atoms, and the hydrogen atoms attached to C15, C16 and C17 are disordered over two sites, with refined occupancies of 0.309 (7) and 0.691 (7) (Fig. 1). The bond lengths involving atom C9 indicate a degree of electron delocalization (Yuan et al., 2006). As can be seen from the packing diagram (Fig. 2), intermolecular N—H···N and C—H···O hydrogen bondings (Table 1) link the molecules.
