N-(2-Methylphenyl)benzenesulfonamide

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

Abstract top

In the title compound, C13H13NO2S, the conformation of the N-H bond is anti to the ortho-methyl group on the aniline ring, in contrast to the syn conformation observed with respect to the ortho-chloro group in N-(2-chlorophenyl)benzenesulfonamide. The dihedral angle between the two benzene rings is 61.5 (1)°. Molecules are linked into chains running along the a axis by N-H...O hydrogen bonds.

Comment top

As part of a study of the substituent effects on the crystal structures of N-(aryl)-sulfonamides the structure of N-(2-methylphenyl)-benzenesulfonamide (N2MPBSA) has been determined (Gowda et al., 2007a,b, 2008). The conformations of the N—H and S═O bonds of the SO2—NH—C group are trans to each other (Fig. 1). Further, the conformation of the N—H bond is anti to the ortho-methyl group in the aniline benzene ring, in contrast to the syn conformation observed with respect to the ortho-chloro group in N-(2-chlorophenyl)-benzenesulfonamide (N2CPBSA) (Perlovich et al., 2006). The two benzene rings are rotated relative to each other by 61.5 (1)° compared to the value of 49.1 (1)° in N2CPBSA. The other bond parameters in N2MPBSA are similar to those in N2CPBSA and other N-(aryl)-sulfonamides (Gelbrich et al., 2007; Gowda et al., 2007a,b, 2008).

In the crystal structure of N2MPBSA (Fig. 1), the molecules are linked into chains running along the a axis by N—H···O hydrogen bonds (Table 1).

Experimental top

A solution of benzene (10 ml) in chloroform (40 ml) was treated dropwise with chlorosulfonic acid (25 ml) at 273 K. 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 o-toluidine in the stoichiometric ratio and boiled for 10 min. The reaction mixture was then cooled to room temperature and added to ice cold water (100 ml). The resultant solid N-(2-methylphenyl)-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). Single crystals of the title compound used for X-ray diffraction studies were grown by slow evaporation of an ethanolic solution at room temperature.

Refinement top

H atoms of the methyl group were positioned geometrically and refined using a riding model, with C-H = 0.96 Å and Uiso(H) = 1.5Ueq(C). The remaining H atoms were located in a difference map and their positional parameters were refined [N-H = 0.82 (3) Å, C-H = 0.88 (4)–1.00 (4) Å] with Uiso(H) = 1.2Ueq(C,N). Three most deviating reflections (0 1 1, 0 1 2, 0 1 3) were omitted from the refinement.

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.
