Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)

Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)

Acyclic diene metathesis polymerization or ADMET polymerization involves cross-metathesis of terminal dienes, such as 1,8-nonadiene, to give linear unsaturated polymer and ethylene. As ADMET is a reversible process, the formed ethylene gas must be removed from the reaction mixture to complete the polymerization process.
Similar to cross-metathesis, ADMET also involves the formation of metallacyclobutane intermediate by [2+2] cycloaddition of one of the double bonds of a terminal diene with...

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...

Thermal and Photochemical Electrocyclic Reactions: Overview

Thermal and Photochemical Electrocyclic Reactions: Overview

Electrocyclic reactions are reversible reactions. They involve an intramolecular cyclization or ring-opening of a conjugated polyene. Shown below are two examples of electrocyclic reactions. In the first reaction, the formation of the cyclic product is favored. In contrast, in the second reaction, ring-opening is favored due to the high ring strain associated with cyclobutene formation.

Phase Diagrams of Ternary Systems

Phase Diagrams of Ternary Systems

Consider a ternary system, which is composed of three components: water (W), ethanoic acid (E), and trichloromethane (T). Here, Ethanoic acid (E) is fully miscible with both water (W) and trichloromethane (T), meaning it can mix entirely with either of them. However, water and trichloromethane have partial miscibility, meaning they can only mix to a certain extent, beyond which two separate phases will form.The phase diagram of a ternary system is represented as an equilateral triangle, where...

[4+2] Cycloaddition of Conjugated Dienes: Diels–Alder Reaction

[4+2] Cycloaddition of Conjugated Dienes: Diels–Alder Reaction

The Diels–Alder reaction is an example of a thermal pericyclic reaction between a conjugated diene and an alkene or alkyne, commonly referred to as a dienophile. The reaction involves a concerted movement of six π electrons, four from the diene and two from the dienophile, forming an unsaturated six-membered ring. As a result, these reactions are classified as [4+2] cycloadditions.

Background:

Organyl ethynyl tellurides represent a class of organotellurium compounds with potential applications in materials science and organic synthesis.
Structural characterization of novel organotellurium compounds is crucial for understanding their chemical properties and reactivity.
The synthesis and investigation of compounds featuring tellurium-carbon bonds contribute to the broader field of organotellurium chemistry.

Purpose of the Study:

To report the first structural characterization of an organyl ethynyl telluride, specifically R-Te-C≡C-H.
To elucidate the molecular geometry, bonding characteristics, and intermolecular interactions of the title compound.
To investigate the crystal packing and supramolecular assembly driven by non-covalent interactions.

Main Methods:

Single-crystal X-ray diffraction was employed to determine the three-dimensional structure of the title compound.
Analysis of bond lengths, bond angles, and coordination geometry around the tellurium atom.
Identification and analysis of intermolecular interactions, including hydrogen bonds and Te⋯π interactions, within the crystal lattice.

Main Results:

The title compound, C(10)H(11)NTe, is the first organyl ethynyl telluride to be structurally characterized.
The molecule exhibits an L-shaped geometry with distinct Te-Csp(2) and Te-Csp bond lengths and an angular C-Te-C coordination.
Crystal structure reveals Csp-H⋯N hydrogen bonds and Te⋯π(aryl) interactions, leading to the formation of zigzag ribbons.
