2,2-Dichloro-N-(4-chloro-phenyl-sulfon-yl)-acetamide
Abstract:
In the crystal structure of the title compound (N4CPSDCAA), C(8)H(6)Cl(3)NO(3)S, the conformations of the N-H and C=O bonds in the SO(2)-NH-CO-C group are trans to each other, similar to those observed in 2,2-dichloro-N-(phenyl-sulfon-yl)-acetamide (NPSDCAA), 2,2-dichloro-N-(4-methyl-phenyl-sulfon-yl)acetamide (N4MPSDCAA) and N-(4-chloro-phenyl-sulfon-yl)-2,2,2-trimethyl-acetamide (N4CPSTMAA), with similar bond parameters. The -SNHCOC- unit in N4CPSDCAA is essentially planar and makes a dihedral angle of 79.67 (5)° with the benzene ring, comparable to 79.75 (8)° in NPSDCAA, 81.02 (5)° in N4MPSDCAA and 82.2 (1)° in N4CPSTMAA. The mol-ecules in N4CPSDCAA are linked into layers parallel to the (001) plane by inter-molecular N-H⋯O hydrogen bonds.

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.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
Carboxylic Acid Derivatives: Overview
Preparation of Acid Anhydrides
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...
Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
