Crystal Structure of N-allyl-4-methylbenzenesulfonamide

The title compound, C10H13NO2S, was synthesized by a nucleophilic substitution reaction between allyl amine and p-toluenesulfonyl chloride. The sulfonate S—O bond lengths are 1.4282 (17) and 1.4353 (17) Å, and the C—N—S—C torsion angle involving the sulfonamide moiety is −61.0 (2)°. In the crystal, centrosymmetric dimers of the title compound are present via intermolecular N—H...O hydrogen bonds between sulfonamide groups. These dimers are linked into ribbons along the c-axis direction through offset π–π interactions.
