Summary
This study details the crystal structure of a chloro-substituted amide compound. Molecular analysis reveals specific bond orientations and intermolecular hydrogen bonding, influencing its solid-state arrangement.
Area of Science:
- Crystallography
- Organic Chemistry
- Molecular Structure
Background:
- Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties and reactivity.
- Amide compounds are fundamental in organic chemistry, playing roles in biological systems and materials science.
- Detailed structural analysis provides insights into intermolecular forces and crystal packing.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(15)H(14)ClNO.
- To analyze the spatial arrangement of functional groups, specifically the amide moiety and substituted aromatic rings.
- To investigate the intermolecular interactions governing the crystal packing.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Geometric parameters, including bond lengths, bond angles, and dihedral angles, were precisely measured.
- Analysis of intermolecular interactions, such as hydrogen bonding, was performed.
Main Results:
- The N-H and C=O bonds of the amide group were found to be in an anti configuration.
- The amide group exhibited specific inclinations relative to the chloro-benzoyl and dimethyl-aniline rings (60.3° and 59.2°, respectively).
- A small dihedral angle (7.7°) was observed between the two benzene ring planes, and molecules formed chains via N-H⋯O hydrogen bonds.
Conclusions:
- The study provides a precise description of the molecular geometry and crystal packing of C(15)H(14)ClNO.
- The observed anti-amide conformation and specific ring inclinations are key structural features.
- Intermolecular hydrogen bonding dictates the formation of one-dimensional chains in the crystal lattice.

01:11Nucleophilic Aromatic Substitution: Elimination–Addition
Simple aryl halides do not react with nucleophiles. However, nucleophilic aromatic substitutions can be forced under certain conditions, such as high temperatures or strong bases. The mechanism of substitution under such conditions involves the highly unstable and reactive benzyne intermediate. Benzyne contains equivalent carbon centers at both ends of the triple bond, each of which is equally susceptible to nucleophilic attack. This 50–50 distribution of products is confirmed through isotopic...
01:10Hydrolysis of Chlorobenzene to Phenol: Dow Process
Simple aryl halides do not react with nucleophiles under normal conditions. However, the reaction can proceed under drastic conditions involving high temperatures and high pressure to give the substituted products. For example, chlorobenzene is converted to phenol using aqueous sodium hydroxide at 350 °C under high pressure by the Dow process. The reaction follows an elimination-addition mechanism involving a benzyne intermediate. Here, the chloride ion is eliminated to generate the benzyne...

Benzylic halogenation takes place under conditions that favor radical reactions such as heat, light, or a free radical initiator like peroxide.
01:20Diazonium Group Substitution with Halogens and Cyanide: Sandmeyer and Schiemann Reactions
Arenediazonium substitution reactions occur when the diazonium group is substituted by various functional groups such as halides, hydroxyl, nitrile, etc. For instance, arenediazonium salts react with copper(I) salts of chloride, bromide, or cyanide to form corresponding aryl chlorides, bromides, and nitriles. These reactions are named Sandmeyer reactions. Although the mechanism of this reaction is complicated, as illustrated in Figure 1, they are believed to progress via an aryl copper...
01:11Nomenclature of Aromatic Compounds with Multiple Substituents
When more than one substituent is present on the benzene ring, the IUPAC nomenclature depends on the number of substituents present.
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...

01:15Electrophilic Aromatic Substitution: Chlorination and Bromination of Benzene
Chlorination and bromination are important classes of electrophilic aromatic substitutions, where benzene reacts with chlorine or bromine in the presence of a Lewis acid catalyst to give halogenated substitution products. A Lewis acid such as aluminium chloride or ferric chloride catalyzes the chlorination, and ferric bromide catalyzes the bromination reactions. During the bromination of alkenes, bromine polarizes and becomes electrophilic. However, in the bromination of benzene, the bromine...
