N,N'-Bis(4-chloro-phenyl-sulfon-yl)-adipamide
Abstract:
In the title compound, C(18)H(18)Cl(2)N(2)O(6)S(2), the asymmetric unit contains half a mol-ecule with a center of symmetry at the mid-point of the central C-C bond. The dihedral angle between the benzene ring and the SO(2)-NH-C(O) segment in the two halves of the mol-ecule is 83.5 (2)°. In the crystal, N-H⋯O(S) inter-molecular hydrogen bonds link the mol-ecules into infinite chains running along the c axis. The O atom involved in the hydrogen bond has a longer S-O bond than the other O atom bonded to S [1.403 (4) versus 1.361 (4) Å].

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
