1-(2,6-Difluorobenzoyl)-3-(2,3,5-trichlorophenyl)urea

S.-J. Yan, C. Huang, Y.-M. Li, Y.-Y. Yan and J. Lin

The asymmetric unit of the title compound, C₁₄H₇Cl₃F₂N₂O₂, contains two unique molecules. The 2,3,5-trichlorophenyl ring is almost coplanar with the urea group in both molecules, whereas the 2,6-difluorophenyl ring is twisted from the urea plane by 54.83 (10)° in one molecule and 60.58 (10)° in the other. An intramolecular N—H—O hydrogen bond stabilizes the molecular conformation. The crystal packing is formed by intermolecular N—H—O hydrogen bonds and F

F interactions [2.841 (2) Å].

Comment top

Derivatives of benzoylphenylureas (BPUs) are kind of insect growth regulators (IGRs), interferes the chitin synthesis in target pests, causing death or abortive development. BPUs posses high selectivity, low acute toxicity for mammals. At the time, the different groups on the phenyl that have different bioactivity. So research the configuration of the different compound is important to find more potent insecticide. The title compound (I) (Fig. 1), C₁₄H₇Cl₃F₂N₂O₂, which possesses high bioactivity to pests (Yan et al., 2003).

The geometrical parameters for (I) (Table 1) show the conjugation present: the length of the C1═O1 and C═O2 double bond is greater than that of a normal C═O double bond. The lengths of the C1—N1, C1—N2, C8—N2 bonds are shorter than that of normal C—N single bonds. The 2,3,5-trichlorophenyl ring of the title compound is almost coplanar with the urea group, whereas the 2,6-difluorophenyl ring is twisted from the urea plane by 60.58 (10)°. An intramolecular N—H—O hydrogen bond stabilizes the molecular conformation. The crystal packing of the title compound formed by intermolecular N—H—O hydrogen bonds and F···F bond (Fig 2).

Experimental top

A solution of 2,6-difluorobenzoyl isocyanate (II) (10 mmol, 1.0 equiv.) in 1,2-dichloroethane (10 ml) was added to a stirred solution of 2,3,5-trichloroaniline (III) (10 mmol, 1.0 equiv.) in dry 1,2-dichloroethane (20 ml) and stirred at room temperature for 24 hrs, the solvent was removed in vacuo and the residue was recrystallized with ethyl acetate to give desired compounds as white needle-crystals (I) in 93% yield (Lin et al., 2003; Lin et al., 2005). The desire product recrystallized from acetone (m.p. 517 K).

Special details top

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.
