Basicity of Heterocyclic Aromatic Amines

Basicity of Heterocyclic Aromatic Amines

Heterocyclic amines, where the N atom is a part of an alicyclic system, are similar in basicity to alkylamines. Interestingly, the heterocyclic amine having a nitrogen atom as part of an aromatic ring has much less basicity than its corresponding alicyclic counterpart. For this reason, as presented in Figure 1, piperidine (pKb = 2.8) is significantly more basic than pyridine (pKb = 8.8).

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT) is an advanced Nuclear Magnetic Resonance (NMR) technique specifically designed to detect and enhance the signals of low-abundance nuclei, such as carbon-13 and nitrogen-15, in small molecules. The fundamental principle behind INEPT is the transfer of polarization from a more abundant and highly polarizable nucleus, typically hydrogen-1, to the low-abundance nucleus of interest. This process effectively boosts the NMR signal of the...

2° Amines to N-Nitrosamines: Reaction with NaNO₂

Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.

Area of Science:

Crystallography
Solid-state chemistry
Supramolecular chemistry

Background:

Understanding the intermolecular forces that dictate crystal packing is crucial in materials science.
Hydrogen bonding plays a significant role in the self-assembly of molecules in the solid state.
The specific arrangement of molecules in a crystal lattice influences the material's physical and chemical properties.

Purpose of the Study:

To elucidate the crystal structure of the title compound, C(5)H(3)IN(2)O(2).
To identify and characterize the intermolecular interactions present in the crystal lattice.
To understand how these interactions lead to the formation of extended structures.

Main Methods:

Single-crystal X-ray diffraction was employed to determine the three-dimensional crystal structure.
Analysis of the crystal structure involved identifying hydrogen bond donors and acceptors.
Intermolecular interactions were systematically analyzed using crystallographic software.

Main Results:

The crystal structure of C(5)H(3)IN(2)O(2) was successfully determined.
A key finding is the presence of intermolecular C-H⋯N hydrogen bonding interactions.
These interactions link individual molecules into one-dimensional chains extending along the b axis.

Conclusions:

The crystal structure is stabilized by a network of C-H⋯N hydrogen bonds.
The observed one-dimensional chain formation is a direct consequence of these specific intermolecular interactions.
This structural motif provides insights into the supramolecular assembly of related compounds.
