N-Cyclo­hexyl-4-meth­yl-N-propyl­benzene­sulfonamide

The title compound, C₁₆H₂₅NO₂S, is a sulfonamide derivative with the substitution of propyl and cyclo­hexyl groups at the N atom. The least-squares plane through all six C atoms of the cyclo­hexyl ring forms a dihedral angle of 58.88 (12)° with the toluene ring. No hydrogen-bonding inter­actions are present in the crystal structure.

Supporting information

S1. Comment

The title compound (I) is an analogue to the structures (II) and (III) already published by our group (Haider et al., 2009, 2010). The cyclohexyl ring adopts the chair form, and it is orientented with the least-squares plane of all six carbon atoms at the dihedral angle of 58.88 (12)° with respect to the aromatic ring. This angle compares well with the analogous angle in (III) (59.92 (6)°) but differs slightly from that found in (II) (50.13 (9)°). Likewise, in the title compound (see Fig. 2) and in (II), no hydrogen bonding interaction was observed in the structure.

S2. Experimental

A mixture of N-cyclohexyl-4-methyl benzene sulfonamide (1.089 g, 4.3 mmol), and sodium hydride (0.21 g, 8.6 mmol) in N, N-dimethylformamide (10 ml) was stirred at room temperature for half an hour followed by addition of propyl iodode ( 8.6 mmol). Stirring was continued further for a period of three hours and the contents were poured over crushed ice. The precipitated product was isolated, washed and crystallized from methanol solution by slow evaporation.

S3. Refinement

The C—H H-atoms were positioned gemetrically and were refined using a riding model with C–H = 0.93 Å and U_iso(H) = 1.2 U_eq for aromatic (C), with C–H = 0.97 Å and U_iso(H) = 1.2 U_eq for methylene (C), and with C–H = 0.98 Å and U_iso(H) = 1.2 U_eq for (C7). The low angle reflection (0 2 0) was omitted in the final refinement and the H-atoms for methyl (C13) were refined at two positions using the HFIX 127 command in SHELXL97 with C–H = 0.96 Å and U_iso(H) = 1.5 U_eq for (C13).

Special details

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
