Summary
Researchers developed a novel nickel catalyst for converting nitrogen oxide (NO) into valuable products. This synthetic approach achieves efficient deoxygenation and C-N coupling under mild conditions, producing oximes from benzyl halides.
Area of Science:
- Catalysis
- Organometallic Chemistry
- Green Chemistry
Background:
- Nitrogen oxide (NO) conversion is crucial for the global nitrogen cycle.
- Biological NO transformation is well-studied, but synthetic approaches are needed for value-added products.
Purpose of the Study:
- To devise a synthetic, bifunctional metal catalyst for NO conversion.
- To develop a novel nickel pincer system for efficient NO deoxygenation and C-N coupling.
Main Methods:
- Utilized a Ni pincer catalyst for NO deoxygenation using CO(g).
- Investigated the transfer of the nitroso group to organic substrates via nucleophilic reaction.
- Employed experimental and theoretical methods to evaluate the catalytic activation of alkyl halides.
Main Results:
- Successfully converted NO to Ni-NO and then to Ni-NO via deoxygenation.
- Achieved catalytic production of oximes from benzyl halides with a turnover number >200.
- Demonstrated a nickel(I)-NO species effectively activates alkyl halides.
Conclusions:
- The developed nickel catalyst is bifunctional, performing both NO deoxygenation and C-N coupling.
- This novel catalytic system offers a synthetic route to valuable products from NO under mild conditions.

02:23SN2 Reaction: Stereochemistry
10.0K
In an SN2 reaction, the nucleophilic attack on the substrate and departure of the leaving group occurs simultaneously through a transition state. As the nucleophile approaches the substrate from the back-side, the configuration of the substrate carbon changes from tetrahedral to trigonal bipyramidal and then back to tetrahedral, leading to an inversion in the configuration of the product.
If the substrate is an achiral molecule at the α-carbon, the inversion of configuration is not...

02:10Reduction of Alkynes to trans-Alkenes: Sodium in Liquid Ammonia
9.7K
Alkynes can be reduced to trans-alkenes using sodium or lithium in liquid ammonia. The reaction, known as dissolving metal reduction, proceeds with an anti addition of hydrogen across the carbon–carbon triple bond to form the trans product. Since ammonia exists as a gas (bp = −33°C) at room temperature, the reaction is carried out at low temperatures using a mixture of dry ice (sublimes at −78°C) and acetone.

3.5K
Ziegler–Natta polymerization is another form of addition or chain‐growth polymerization used for synthesizing linear polymers over branched polymers. The catalyst used for polymerization is the Ziegler–Natta catalyst, named after Karl Ziegler and Giulio Natta, who developed it in 1953. This catalyst is an organometallic complex of titanium tetrachloride and triethyl aluminum, with the active form of the catalyst being an alkyl titanium compound. Using the Ziegler–Natta...

02:17Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
3.5K
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...

01:13meta-Directing Deactivators: –NO2, –CN, –CHO, –CO2R, –COR, –CO2H
6.0K
All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...

02:26SN2 Reaction: Transition State
10.3K
An SN2 reaction of an alkyl halide is a single-step process in which bond formation between the nucleophile and the substrate and bond breaking between the substrate and the halide occurs simultaneously through a transition state without forming an intermediate.
When the nucleophile approaches the electrophilic carbon with its lone pairs, the halide acts as a leaving group and moves away with the electron-pair bonded to the carbon. Dotted partial bonds represent the bonds being formed or broken...
