3-Chloro-N-(4-meth-oxy-phen-yl)propanamide
Abstract:
The title compound, C(10)H(12)ClNO(2), is a halogenated derivative of a secondary amide bearing an aromatic substituent. The C(=O)-N(H)-C(ar)-C(ar) torsion angle of -33.70 (18)° rules out the presence of resonance spanning the amide as well as the aromatic system. In the crystal, classical N-H⋯O hydrogen bonds, as well as C-H⋯O contacts connect the mol-ecules into chains propagating along the a axis.

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.

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...
