Chirality at Nitrogen, Phosphorus, and Sulfur

Chirality at Nitrogen, Phosphorus, and Sulfur

Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, phosphorus and sulfur centers, including trivalent molecules with lone pairs. Here, the lone pair behaves as a functional group in addition to the other three substituents to form an analogous tetrahedral center that can be chiral.
A consequence of chirality is the need for enantiomeric resolution. While this is theoretically possible for all...

Preparation and Reactions of Sulfides

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.

Preparation and Reactions of Thiols

Thiols are prepared using the hydrosulfide anion as a nucleophile in a nucleophilic substitution reaction with alkyl halides. For instance, bromobutane reacts with sodium hydrosulfide to give butanethiol.

Area of Science:

Inorganic Chemistry
Crystallography
Materials Science

Background:

The study investigates a novel antimony-containing compound with the formula [Sb(C(6)H(5))(3)(N(2)S(2))].
This compound shares structural similarities with a previously identified polymorph of Sb(S(2)N(2))Ph(3).

Purpose of the Study:

To characterize the molecular structure and bonding of the title compound, [Sb(C(6)H(5))(3)(N(2)S(2))].
To compare its structure with the known polymorph of Sb(S(2)N(2))Ph(3) and analyze differences in phenyl ring orientation.

Main Methods:

Crystallographic analysis to determine the precise arrangement of atoms and molecules in the solid state.
Spectroscopic techniques to confirm the compound's identity and purity.

Main Results:

The title compound, [Sb(C(6)H(5))(3)(N(2)S(2))], was synthesized and structurally characterized.
A key finding is the difference in phenyl ring orientation compared to the known polymorph of Sb(S(2)N(2))Ph(3).
The S-N-S-N unit exhibits a unique bond order distribution: one long S-N bond, an intermediate N=S bond, and a short S=N bond.

Conclusions:

The structural characterization of [Sb(C(6)H(5))(3)(N(2)S(2))] reveals subtle yet significant differences from its known polymorph.
The observed bond order in the SNSN unit provides insights into the electronic structure and bonding characteristics of this inorganic ring system.
