In the title compound, C12H12ClNO2S, the S atom is displaced by 0.708 (2) Å out of the plane through the remaining atoms of the thia­zine ring (r.m.s. deviation = 0.0823 Å). This plane makes a dihedral angle of 89.33 (7)° with the phenyl ring. In the crystal, adjacent mol­ecules are connected through C—H⋯O hydrogen bonds into layers parallel to the bc plane.

Comment top

Sultones are cyclic sulfonate esters of hydroxy sulfonic acids and may be saturated or unsaturated. It is well known that the reaction of unsaturated sultones with primary amines forms the corresponding sultams, a cyclic sulfonamide in which the S—N bond is part of the ring (Imam Ismail, 1990). The title sultam compound was obtained through the reaction of the sultone, 4,6-dimethyl-2,2-dioxo-1,2-oxathiine, with p-chloroaniline. Similar to what was observed in the structure of the 4-methoxyphenyl analogue (Fanghanel et al., 1998), the thiazine ring adopts a half-chair conformation with the S atom displaced by 0.708 (2) Å from the plane passing through the remaining five atoms of the ring, C2,C3,C4,C6 and N1. This plane and the phenyl ring make a dihedral angle of 89.33 (7)°. In the crystal, intermolecular C—H···O hydrogen bonds connect the molecules to form a two-dimensional network parallel to the bc plane (Table 1).

Experimental top

A mixture of 4,6-dimethyl-2,2-dioxo-1,2-oxathiine (1.6 g, 0.01 mol) and p-chloroaniline (1.28 g, 0.01 mol) in a conical flask was heated at 150°C for an hour. The content was cooled to room temperature and then washed with an aqueous solution (10 ml) of HCl (0.1 N). The white solid was collected, washed with water and dried over silica-gel. The X-ray quality crystals were obtained from a methanol solution at room temperature.

Refinement top

Hydrogen atoms were placed at calculated positions at distances H—Csp2 = 0.95 Å and HCmethyl= 0.98 Å and were treated as riding on their parent atoms, with Uiso(H) = 1.2 (1.5 for methyl)Ueq(C).

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.
