Aldehydes and Ketones with HCN: Cyanohydrin Formation Overview

Aldehydes and Ketones with HCN: Cyanohydrin Formation Overview

Cyanohydrins are compounds that contain –CN and –OH groups on the same carbon atom. They are formed by the nucleophilic addition of the cyanide ions to the carbonyl group. Cyanide ions are highly basic and nucleophilic and can be generated from HCN under aqueous conditions. However, since HCN is a weak acid, the number of cyanide ions generated is very small. Hence, a small amount of base or KCN/NaCN is added to HCN to increase the concentration of the cyanide ions in the reaction mixture.

Aromatic Hydrocarbon Cations: Structural Overview

Aromatic Hydrocarbon Cations: Structural Overview

Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.
Removing one hydrogen from the intervening CH2 group with both...

Area of Science:

Crystallography
Supramolecular Chemistry
Chemical Synthesis

Background:

Trithio-cyanuric acid is a sulfur-containing heterocyclic compound.
Tripropyl-amine is a tertiary amine.
Amine-acid interactions can lead to salt formation and unique crystal structures.

Purpose of the Study:

To synthesize and characterize a new salt formed between trithio-cyanuric acid and tripropyl-amine.
To investigate the structural features and intermolecular interactions within the synthesized salt.

Main Methods:

Single-crystal X-ray diffraction was employed to determine the crystal structure.
Analysis of bond lengths, bond angles, and intermolecular contacts (N-H⋯S, N-H⋯N) was performed.

Main Results:

The salt, tripropyl-ammonium trithio-cyanurate, was successfully synthesized.
The crystal structure reveals coplanar trithio-cyanurate and tripropyl-ammonium ions with a dihedral angle of 82.33(8)°.
The salt is stabilized by a network of N-H⋯S and N-H⋯N hydrogen bonds.

Conclusions:

The proton transfer from trithio-cyanuric acid to tripropyl-amine results in the formation of ammonium and trithio-cyanurate ions.
The observed coplanarity and hydrogen bonding network dictate the supramolecular architecture of the salt.
