C–C Coupling in sterically demanding porphyrin environments [PDF]

Beilstein Journal of Organic Chemistry
Unlike their planar counterparts, classic synthetic protocols for C–C bond forming reactions on nonplanar porphyrins are underdeveloped. The development of C–C bond forming reactions on nonplanar porphyrins is critical in advancing this field of study ...

Ligand-tuning copper in coordination polymers for efficient electrochemical C–C coupling [PDF]

Nature Communications
Cu catalyses electrochemical CO2 reduction to valuable multicarbon products but understanding the structure-function relationship has remained elusive due to the active Cu sites being heterogenized and under dynamic re-construction during electrolysis ...

Asymmetric gradient orbital interaction of hetero-diatomic active sites for promoting C − C coupling [PDF]

Nature Communications, 2023
Diatomic-site catalysts (DACs) garner tremendous attention for selective CO2 photoreduction, especially in the thermodynamical and kinetical mechanism of CO2 to C2+ products.

On-surface synthesis platform for highly branched oligomers based on sequential C—C coupling and C—H activation of carbenes [PDF]

Nature Communications
On-surface synthesis is an emerging field for fabricating low-dimensional nanostructures. While carbenes are versatile reactive intermediates in solution-phase organic synthesis, they have rarely been explored in on-surface synthesis.

Efficient methanol upcycling to ethylene glycol and glycolaldehyde via divergent C−C coupling synthesis [PDF]

Nature Communications
Direct photocatalytic conversion of methanol into high-value multi-carbon chemicals through precisely controlled C − C coupling represents an extremely appealing but challenging goal. Herein, we demonstrate the efficient photoredox-driven dehydrocoupling

Lattice Carbon‐Mediated Ultralow‐Barrier C–C Coupling for Selective CO Electroreduction to Ethylene [PDF]

Advanced Science
Understanding the mechanistic pathways of catalytic CO2 reduction is essential for the rational design of high‐performance electrocatalysts. A key challenge in converting CO2 to multi‐carbon (C2+) products is the high energy barrier for C─C coupling ...

Demethylation C–C coupling reaction facilitated by the repulsive Coulomb force between two cations [PDF]

Nature Communications
Carbon chain elongation (CCE) is normally carried out using either chemical catalysts or bioenzymes. Herein we demonstrate a catalyst-free approach to promote demethylation C–C coupling reactions for advanced CCE constructed with functional groups under ...
