Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

Catalytic hydrogenation of alkenes is a transition-metal catalyzed reduction of the double bond using molecular hydrogen to give alkanes. The mode of hydrogen addition follows syn stereochemistry.
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation

Introduction
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.

Preparation of Nitriles

Preparation of Nitriles

One of the common methods to prepare nitriles is the dehydration of amides. This method requires strong dehydrating agents like phosphorous pentoxide or boiling acetic anhydride for converting amides to nitriles. Another reagent namely, thionyl chloride also accomplishes the dehydration of amides, where amide acts as a nucleophile. The first step of the mechanism involves the nucleophilic attack by the amide on the thionyl chloride to form an intermediate. In the next step, the electron pairs...

Diels–Alder Reaction Forming Cyclic Products: Stereochemistry

Diels–Alder Reaction Forming Cyclic Products: Stereochemistry

The Diels–Alder reaction is one of the robust methods for synthesizing unsaturated six-membered rings. The reaction involves a concerted cyclic movement of six π electrons: four π electrons from the diene and two π electrons from the dienophile.

Benzene to 1,4-Cyclohexadiene: Birch Reduction Mechanism

Benzene to 1,4-Cyclohexadiene: Birch Reduction Mechanism

Birch reduction uses solvated electrons as reducing agents. The reaction converts benzene to 1,4-cyclohexadiene. The reaction proceeds by the transfer of a single electron to the ring to form a benzene radical anion. This anion is highly basic—it abstracts a proton from the alcohol to form a cyclohexadienyl radical. Another single electron transfer gives the cyclohexadienyl anion. A proton transfer from the alcohol forms 1,4-cyclohexadiene. Since this reduction occurs via radical anion...

Preparation of Amines: Reduction of Oximes and Nitro Compounds

Preparation of Amines: Reduction of Oximes and Nitro Compounds

Oximes can be reduced to primary amines using catalytic hydrogenation, hydride reduction, or sodium metal reduction. The reduction of aliphatic and aromatic nitro compounds to primary amines takes place by either catalytic hydrogenation or by using active metals like Fe, Zn, and Sn in the presence of an acid.
Though catalytic hydrogenation can reduce nitrobenzenes, the reduction is nonselective in the presence of other functional groups. For instance, if nitrobenzene contains an aldehyde group,...

Background:

Graphdiynes (GDYs) are 2D materials with diverse electronic properties, but 3D crystalline frameworks remain synthetically challenging.
Developing 3D covalent organic frameworks (COFs) with pure carbon skeletons and tunable optoelectronic properties is crucial for advanced applications.

Purpose of the Study:

To synthesize highly crystalline, 3D GDY-like frameworks with ThSi2 topology using naphthalene and azulene-based monomers.
To investigate the structure-property relationships and catalytic performance of these novel COFs, particularly for ammonia electrocatalysis.

Main Methods:

Synthesis of 3D GDY-like frameworks via direct coupling of arylacetylenes.
Characterization of framework topology, electronic structure (bandgap, HOMO/LUMO levels), and porosity.
Electrocatalytic evaluation for ammonia synthesis using ruthenium single-atom supported frameworks.

Main Results:

Two isomeric, highly crystalline 3D GDY-like frameworks with ThSi2 topology were successfully synthesized.
The azulene-based framework exhibited a significantly narrower bandgap (1.15 eV) compared to the naphthalene counterpart (2.33 eV) due to its large dipole moment.
Ruthenium single-atom catalysts supported on these frameworks achieved high ammonia yield rates (188.7 ± 1.6 µg h⁻¹ mg⁻¹) and Faradaic efficiency (37.4 ± 0.6%).
The azulene-based framework demonstrated superior electron mobility owing to its optimized HOMO and LUMO energy levels.

Conclusions:

The study introduces a new family of 3D crystalline COFs with diyne linkages and pure carbon skeletons.
These frameworks offer a tunable platform for optoelectronic properties and catalysis, broadening the scope of COF materials.
The well-defined structures facilitate fundamental studies on structure-property relationships and open avenues for catalytic and electronic applications.
