The title compound was prepared according to the method of Liu et al. (2006). 3-((E)-2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2- dimethylcyclopropanecarboxylic acid (0.97 g, 4.0 mmol) was dispersed in SOCl2 (15 ml), and a drop of anhydrous DMF was added. The mixture was heated to reflux for 2 h. SOCl2 was removed by rotoevapor. The crude product could be directly disolved in anhydrous toluene, mixed with 2,5-dimethylbenzenamine (0.50 g, 4.1 mmol). Triethylamine was dropped into the system, and a white fume was coming out. After 8 h stirring at room temperature, the reaction mixture was treated with hexane. Recrystallization of the product from methanol and a small amount of water (70:1) overnight at ambient temperature gave colorless rod like crystals.
H atoms were positioned geometrically with C—H = 0.93–0.98 Å and refined using a riding model with Uiso(H) = 1.2Ueq(C). The amino H atom was located from a difference map and freely refined.

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. |

3-((E)-2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2-dimethyl cyclopropanecarboxylic acid is a very important intermediate for tefluthrin, a important insecticide controlling a wide range of soil insect pests in maize, sugar beet, and other crops (Punja, 1981). 2,5-dimethylbenzenamine containing pesticides have the advantage of low toxicity, high activity and low residues (Zhang, 2005). The title compound containing both these active parts may have some insecticide activity. The present X-ray crystal structure analysis was undertaken in order to study the stereochemistry and crystal packing of the title compound. The dihedral angles between the benzene moiety and the cycloprapane group is 66.7 (3)°. The crystal packing is stabilized by an N—H···O hydrogen bond.
