Two 2,2-dihalo-N-(1-phenylethyl)cyclopropane-1-carboxamides

D. S. Yufit and J. A. K. Howard

The crystal structures of (1R,1′S)-2′,2′-dichloro-N-(1-phenylethyl)cyclopropane-1′-carboxamide, C₁₂H₁₃Cl₂NO, (I), and (1R,1′R)-2′,2′-difluoro-N-(1-phenylethyl)cyclopropane-1′-carboxamide, C₁₂H₁₃F₂NO, (II), have been determined. Both crystals contain two independent molecules with different conformations of the phenylethyl groups. In the crystals of both compounds, the molecules are linked together by N—H

O hydrogen bonds, thus forming chains in the a direction.

Comment top

The title compounds have been synthesized as intermediate products in the synthesis of novel ferroelectric liquid crystals with optically active dihaloid-substituted cyclopropanecarboxylic acids in their side chain (Miyazawa & de Meijere, 2001). An X-ray structural study has confirmed the absolute configuration of the molecules, which was proposed on the basis of chemical information.

The structures of (I) and (II) are similar but not isostructural. The structures of both compounds contain two independent molecules, and the conformations of these independent molecules are different. However, in (II) the two independent molecules differ mainly by the orientation of the phenyl ring, whereas in (I) the conformation around the N—C7 bonds in the two independent molecules is also different (Fig. 1). The replacement of chlorine substitutents in the cyclopropane cycle of (I) with more electronegative fluorine substitutents in (II) results in a predictable (e.g. Allen, 1980; Cremer & Kraka, 1985) increase in the asymmetry of the three-membered ring, with a significant elongation of the distal bond C10—C11(C30—C31) and a shortening of the vicinal bonds C12—C10(C32—C30) and C12—C11(C32—C31).

In crystals, the molecules of both compounds form infinite chains along the a axis. The molecules in these chains are connected by strong N—H···O hydrogen bonds. Because the molecules of (I) and (II) have different configurations, the arrangement of the molecules in the chains is also different (Fig. 2). In (I), the phenyl rings and methyl groups of adjacent molecules are in close vicinity, whereas in (II) the C11 methylene groups of the cyclopropane rings are located between the benzene rings. As a result, the chains in (I) are packed together so as to form hydrophobic areas in which the phenylethyl groups are located (Fig. 3), which is not the case in (II).

Experimental top

Crystals of (I) were obtained by the slow evaporation of a hexane/methanol solution. Crystals of (II) were similarly obtained from a hexane/diethyl ether solution.

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.
