Methyl (4-bromo-benzene-sulfonamido)acetate.

ABSTRACT: The title compound, C(9)H(10)BrNO(4)S, is an inter-mediate for the formation of benzothia-zines. In the crystal structure, inter-molecular N-H?O hydrogen bonds link the mol-ecules, forming R(2) (2)(10) ring motifs, which are linked into a two-dimensional polymeric sheet through inter-molecular C-H?O hydrogen bonds.

2-(4-Bromo-benzene-sulfonamido)acetic acid.

Project description:The title compound, C(8)H(8)BrNO(4)S, a halogenated sulfon-amide, was prepared by basic hydrolysis of the methyl ester. In the crystal, mol-ecules form centrosymmetric hydrogen-bonded dimers via the carboxyl groups. These dimers are further linked by N-H?O inter-actions involving the carbonyl O and amide H atoms, forming a ribbon-like structure propagating in [010]. These ribbons are further linked via C-H?O inter-actions, forming a three-dimensional network.

4-(4-Bromo-benzene-sulfonamido)benzoic acid.

Project description:The title compound, C(13)H(10)BrNO(4)S, belongs to the sulfonamide class of organic compounds. The two aromatic rings are inclined at 34.30?(15)° to one another, and the carboxyl substituent lies in the plane of the benzene ring to which it is bound (maximum deviation = 0.004?Å). In the crystal structure, charactersitic carboxylic acid dimers are formed through O-H?O hydrogen bonds. These dimers are linked into rows down a by N-H?O inter-actions. Additional C-H?O contacts further stabilize the structure, and a close Br?Br(x, -y + 1, -z + 1) contact of 3.5199?(9)?Å is also observed.

Cyano-methyl 4-(4-methyl-benzene-sulfonamido)-benzoate.

Project description:The title mol-ecule, C(16)H(14)N(2)O(4)S, adopts an L-shaped conformation, with the central C-S-N-C torsion angle being -69.1?(3)°. The two benzene rings form a dihedral angle of 89.94?(15)°. The mol-ecular conformation may be influenced by a weak intra-molecular C-H?O hydrogen bond which generates an S(6) ring motif. In the crystal, mol-ecules are linked by N-H?O and weak C-H?O hydrogen bonds, forming chains propagating along the b axis. Weak C-H?N hydrogen bonds connect the chains into a two-dimensional network parallel to (011). The crystal studied was an inversion twin, the ratio of components being 0.7?(1):0.3?(1).
