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 ...

Photoenzymes for Radical C-C Coupling. [PDF]

Nat Catal, 2022
General catalytic methods for free radical-mediated asymmetric transformations have long eluded synthetic organic chemists. Now, NAD(P)H-dependent ketoreductases (KREDs) are repurposed and engineered as highly efficient photoenzymes to catalyse asymmetric radical C-C couplings.

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.

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 ...
