2,4-Dichloro-N-(3,5-dimethyl-phen-yl)benzene-sulfonamide
Abstract:
In the crystal of the title compound, C(14)H(13)Cl(2)NO(2)S, the N-H bond in the C-SO(2)-NH-C segment is syn to one of the meta-methyl groups in the aniline benzene ring and anti to the other. Further, the conformation of the N-C bond in the C-SO(2)-NH-C segment is gauche with respect to the S=O bonds. The C-SO(2)-NH-C torsion angle is 54.9 (2)°. The sulfonyl and aniline benzene rings are tilted relative to each other by 82.8 (1)°. The crystal structure features inversion-related dimers linked by pairs of N-H⋯O hydrogen bonds. There are also weak C-H⋯O hydrogen bonds between these dimers.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
