In the 11H14ClNO3S, the conformations of the N—H and C=O bonds in the amide group are anti to each other, similar to those observed in N-phenylsulfonyl-2,2,2-trimethylacetamide (NPSTMAA) and 2,2,2-trimethyl-N-(4-methylphenylsulfonyl)acetamide (N4MPSTMAA). The bond parameters in N4CPSTMAA are similar to those in NPSTMAA, N4MPSTMAA, N-aryl-2,2,2-trimethylacetamides and 4-chlorobenzenesulfonamide. The –SNHCOC– unit including the amide group is essentially planar and makes a dihedral angle of 82.2 (1)° with the benzene ring, comparable to the values of 79.1 (1) and 71.2 (1)° in NPSTMAA and N4MPSTMAA, respectively. The molecules in N4CPSTMAA are linked into a chain by intermolecular N—H⋯O hydrogen bonds.

The title compound was prepared by refluxing 4-chlorobenzenesulfonamide with excess pivalyl chloride for about an hour on a water bath. The reaction mixture was cooled and poured into ice cold water. The resulting solid was separated, washed thoroughly with water and dissolved in warm sodium hydrogen carbonate solution. The title compound was precipitated by acidifying the filtered solution with glacial acetic acid. It was filtered, dried and recrystallized from ethanol. The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared and NMR spectra. Single crystals of the title compound were obtained from an ethanolic solution and used for X-ray diffraction studies at room temperature.
The N-bound H atom was located in a difference map and its positional parameters were refined, with Uiso(H) = 1.2Ueq(N). The refined N—H length is 0.82 (3) Å. The other H atoms were positioned with idealized geometry (C—H = 0.93–0.96 Å) and were refined using a riding model, with Uiso(H) = 1.2Ueq(C).

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. |

In the present work, as part of a study of the substituent effects on the solid state geometries of N-(aryl)-sulfonamides and substituted amides, the structure of N-(4-chlorophenylsulfonyl)-2,2,2-trimethylacetamide (N4CPSTMAA) has been determined (Gowda et al., 2003, 2007, 2008a,b). The conformations of the N—H and C=O bonds of the SO2—NH—CO—C group in N4CPSTMAA are anti to each other (Fig. 1), similar to those observed in N-(phenylsulfonyl)-2,2,2-trimethylacetamide (NPSTMAA) and (4-methylphenylsulfonyl)-2,2,2-trimethylacetamide (N4MPSTMAA) (Gowda et al., 2008a,b). The bond parameters in N4CPSTMAA are similar to those in NPSTMAA, N4MPSTMAA, N-(aryl)-2,2,2-trimethylacetamides (Gowda et al., 2007) and 4-chlorobenzenesulfonamide (Gowda et al., 2003). The packing diagram of N4CPSTMAA molecules showing the hydrogen bonds N—H···O (Table 1) involved in the formation of molecular chains is shown in Fig. 2.
