Oxidative Cleavage of Alkenes: Ozonolysis

Oxidative Cleavage of Alkenes: Ozonolysis

In ozonolysis, ozone is used to cleave a carbon–carbon double bond to form aldehydes and ketones, or carboxylic acids, depending on the work-up.
Ozone is a symmetrical bent molecule stabilized by a resonance structure.

Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide

Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide

Alkenes are converted to 1,2-diols or glycols through a process called dihydroxylation. It involves the addition of two hydroxyl groups across the double bond with two different stereochemical approaches, namely anti and syn. Dihydroxylation using osmium tetroxide progresses with syn stereochemistry.

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.

Radical Autoxidation

Radical Autoxidation

The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

Oxidation of Alkenes: Syn Dihydroxylation with Potassium Permanganate

Oxidation of Alkenes: Syn Dihydroxylation with Potassium Permanganate

Alkenes can be dihydroxylated using potassium permanganate. The method encompasses the reaction of an alkene with a cold, dilute solution of potassium permanganate under basic conditions to form a cis-diol along with a brown precipitate of manganese dioxide.

Background:

Electrochemical oxidation and agglomeration hinder metal-support interactions (MSIs) for efficient oxygen evolution reactions (OER).
Developing stable and active catalysts is crucial for advanced energy technologies like zinc-air batteries.

Purpose of the Study:

To design and synthesize a novel catalyst (Ru-VS₂@CC) that enhances MSIs for efficient OER.
To investigate the catalytic mechanism and durability of the designed electrocatalyst.

Main Methods:

Fabrication of ruthenium (Ru) clusters anchored to vanadium disulfide (VS₂) nanosheets embedded in carbon cloth (CC).
In situ Raman spectroscopy to study the in-situ transformation of Ru clusters.
Theoretical calculations (DFT) to elucidate the electronic structure and catalytic mechanism at the Ru/VS₂ interface.

Main Results:

The Ru clusters electro-oxidized to RuO₂ chainmail, providing catalytic sites and protecting the Ru core via MSIs.
Theoretical calculations revealed optimized intermediate adsorption and reduced migration barriers due to electronic coupling at the Ru/VS₂ interface.
The Ru-VS₂@CC catalyst exhibited ultra-low overpotentials (245 mV at 50 mA cm⁻²) and exceptional stability in zinc-air batteries (470 h).

Conclusions:

The designed Ru-VS₂@CC catalyst effectively addresses challenges in OER catalysis through enhanced MSIs.
This work presents a new strategy for developing highly active and durable electrocatalysts for energy conversion applications.
