Abstract
The title compound, C15H21NO2S, synthesized by N-alkylation of cyclohexylamine benzenesulfonamide with allyl iodide, is of interest as a precursor to biologically active sulfur-containing heterocyclic compounds. The cyclohexane ring is in a chair form and its mean plane makes a dihedral angle of 53.84 (12)° with the phenyl ring.

Comment
Sulfonamides are familiar in the literature for their anti-malarial, anti-convulsant and anti-hypertensive (Connor, 1998; Xiao & Timberlake, 2000; Berredjem et al., 2000; Lee & Lee, 2002) activities. As a part of our ongoing research program regarding the synthesis of sulfur containing heterocyclic compounds (Arshad et al., 2009; Zia-ur-Rehman et al., 2009; Khan et al., 2009), we herein report the crystal structure of the title compound (Fig. 1).
In the title molecule, bond lengths and bond angles are within the normal ranges (Allen et al., 1987). In the crystal structure, the phenyl ring is essentially planar while the cyclohexane ring is in a chair form. No significant hydrogen bond interactions are observed in the title molecule. The dihedral angle between the phenyl and cyclohexane rings is 53.84 (12)°.
Experimental
A mixture of N-cyclohexylbenzene sulfonamide (1.0 g, 0.43 mmol), sodium hydride (0.21 g, 0.88 mmol) and N, N-dimethylformamide (10.0 ml) was stirred at room temperature for half an hour followed by addition of allyl iodide (0.144 g, 0.86 mmol). Stirring was continued further for a period of three hours and the contents were poured over crushed ice. Precipitated product was isolated, washed and crystallized from methanol.
Refinement
All hydrogen atoms were identified in the difference map. However, they were fixed in ideal positions and treated as riding on their parent atoms. The following distances were used: Cmethyl—H = 0.98 Å and Caromatic—H = 0.95 Å. Uiso(H) was set to 1.2Ueq(C) or 1.5Ueq(Cmethyl).

Special details
| 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. |
