N-(2,6-Dimethylphenyl)benzenesulfonamide

B. T. Gowda, S. Foro, K. S. Babitha and H. Fuess

Abstract top

In the crystal structure of the title compound, C14H15NO2S, the N-H bond is trans to one of the S=O double bonds, similar to what is observed in N-(2-methylphenyl)benzenesulfonamide and other aryl sulfonamides. The two aromatic rings enclose a dihedral angle of 44.9 (1)°. The molecules are connected by intermolecular N-H...O hydrogen bonds into chains running along the a axis. An intermolecular C-H...O hydrogen bond is also present.

Comment top

As part of a study of the substituent effects on the crystal structures of N-(aryl)-sulfonamides, in the present work, the structure of N-(2,6-dimethylphenyl)-benzenesulfonamide (N26DMPBSA) has been determined (Gowda et al., 2005, 2008; Gowda, Babitha et al. 2007; Gowda, Foro et al. 2007). The the N—H bond is trans to one of the S—O double bonds (Fig. 1), similar to what is observed in N-(2-methylphenyl)-benzenesulfonamide (N2MPBSA)(Gowda et al., 2008) and other aryl sulfonamides (Perlovich et al., 2006; Gelbrich et al., 2007;). The two aromatic rings are rotated relative to each other by 44.9 (1)°, compared with the value of 61.5 (1)° in N2MPBSA. The other bond parameters in N26DMPBSA are similar to those observed in N2MPBSA and other N-(aryl)-sulfonamides (Gowda, Babitha et al., 2007; Gowda, Foro et al. 2007; Gowda et al. 2008; Perlovich et al., 2006; Gelbrich et al., 2007). The packing diagram of N26DMPBSA via intermolecular N—H···O and C—H···O hydrogen bonds (Table 1) is shown in Fig. 2.

Experimental top

The solution of benzene (10 cc) in chloroform (40 cc) was treated dropwise with chlorosulfonic acid (25 cc) at 0 ° C. After the initial evolution of hydrogen chloride subsided, the reaction mixture was brought to room temperature and poured into crushed ice in a beaker. The chloroform layer was separated, washed with cold water and allowed to evaporate slowly. The residual benzenesulfonylchloride was treated with 2,6-dimethylaniline in the stoichiometric ratio and boiled for ten minutes. The reaction mixture was then cooled to room temperature and added to ice cold water (100 cc). The resultant solid N-(2,6-dimethylphenyl)-benzenesulfonamide was filtered under suction and washed thoroughly with cold water. It was then recrystallized to constant melting point from dilute ethanol. The purity of the compound was checked and characterized by recording its infrared and NMR spectra (Gowda et al., 2005). The single crystals used in X-ray diffraction studies were grown in ethanolic solution by slow evaporation at room temperature.

Refinement top

The H atoms were positioned with idealized geometry using a riding model with C—H = 0.93–0.96 Å, N—H = 0.86 Å, and were refined with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom).

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.
