Summary
The crystal structure of C(11)H(14)N(2)OS reveals specific hydrogen bonding patterns. Molecules form chains through intermolecular N-H⋯S and N-H⋯O interactions, alongside an intramolecular N-H⋯O bond.
Area of Science:
- Crystallography
- Molecular Chemistry
- Supramolecular Chemistry
Background:
- Understanding molecular interactions is crucial in crystal engineering.
- Hydrogen bonding plays a key role in determining crystal packing and properties.
- The title compound, C(11)H(14)N(2)OS, presents an interesting case for structural analysis.
Purpose of the Study:
- To elucidate the crystal structure of C(11)H(14)N(2)OS.
- To identify and characterize hydrogen bonding interactions within the crystal lattice.
- To analyze the resulting supramolecular architecture.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the three-dimensional structure.
- Analysis of hydrogen bond donors and acceptors was performed.
- Topological analysis of hydrogen bond motifs (e.g., S(6), R(2)(2)(8), R(2)(2)(12)) was conducted.
Main Results:
- The crystal structure of C(11)H(14)N(2)OS was successfully determined.
- An intramolecular N-H⋯O hydrogen bond forms an S(6) ring.
- Intermolecular N-H⋯S and N-H⋯O hydrogen bonds link molecules into chains along the [1-10] direction, forming R(2)(2)(8) and R(2)(2)(12) motifs, respectively.
Conclusions:
- The crystal packing of C(11)H(14)N(2)OS is governed by a combination of intramolecular and intermolecular hydrogen bonds.
- The identified hydrogen bonding motifs dictate the formation of one-dimensional chains.
- This structural insight contributes to the understanding of hydrogen bonding in organic compounds.

Preparation of 1° Amines: Gabriel Synthesis
Direct alkylation is not a suitable method for synthesizing amines because it produces polyalkylated products. Gabriel synthesis is the most preferred method to exclusively make primary amines. The method uses phthalimide, which contains a protected form of nitrogen that participates in alkylation only once to predominantly give primary amines.
Strong bases like NaOH or KOH deprotonate the phthalimide to form the corresponding anion, which acts as a nucleophile. Further, the anion attacks an...

Preparation of 1° Amines: Hofmann and Curtius Rearrangement Overview
In the presence of an aqueous base and a halogen, primary amides can lose the carbonyl (as carbon dioxide) and undergo rearrangement to form primary amines. This reaction, called the Hofmann rearrangement, can produce primary amines (aryl and alkyl) in high yields without contamination by secondary and tertiary amines.
Preparation of 1° Amines: Hofmann and Curtius Rearrangement Mechanism
The Hofmann and Curtius rearrangement reactions can be applied to synthesize primary amines from carboxylic acid derivatives such as amides and acyl azides. In the Hofmann rearrangement, a primary amide undergoes deprotonation in the presence of a base, followed by halogenation to generate an N-haloamide. A second proton abstraction produces a stabilized anionic species, which rearranges to an isocyanate intermediate via an alkyl group migration from the carbonyl carbon to the neighboring...
Diazonium Group Substitution: –OH and –H
Nitrous acid, a weak acid, is prepared in situ via the reaction of sodium nitrite with a strong acid under cold conditions. This nitrous acid prepared in situ reacts with primary arylamines to form arenediazonium salts. Such reactions are known as diazotization reactions. As shown in Figure 1, the formation of arenediazonium salts begins with the decomposition of nitrous acid in an acidic solution to give nitrosonium ions.
IUPAC Nomenclature of Aldehydes
Aldehydes are named based on the systematic nomenclature rules set by the IUPAC. For acyclic aldehydes, the longest carbon chain containing the aldehydic (–CHO) group is considered the parent chain. The aldehyde is named by replacing the last letter “e” in the hydrocarbon name with “al”. For instance, a simple, seven-carbon-membered acyclic aldehyde is called heptanal, derived from heptane. The carbon chain is numbered starting from the aldehydic carbon, although the aldehydic carbon’s locant...
Preparation and Reactions of Sulfides
Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.
