Metal-free photoanodes for C-H functionalization. [PDF]

Nat Commun, 2023
Organic semiconductors, such as carbon nitride, when employed as powders, show attractive photocatalytic properties, but their photoelectrochemical performance suffers from low charge transport capability, charge carrier recombination, and self-oxidation.

Photoredox catalysis in nickel-catalyzed C–H functionalization

Beilstein Journal of Organic Chemistry, 2021
Catalytic C‒H functionalization has become a powerful strategy in organic synthesis due to the improved atom-, step- and resource economy in comparison with cross-coupling or classical organic functional group transformations.

Selective ring expansion and C-H functionalization of azulenes. [PDF]

Nat Commun, 2023
We report a transition metal-catalyzed ring expansion of azulene that can be contrasted with C–H functionalization. This study represents the first example of the successful ring expansion of azulene using Cu(hfacac)2 (hfacac: hexafluoroacetylacetonate ...

DABCO-promoted photocatalytic C–H functionalization of aldehydes

Beilstein Journal of Organic Chemistry, 2021
Herein we present a direct application of DABCO, an inexpensive and broadly accessible organic base, as a hydrogen atom transfer (HAT) abstractor in a photocatalytic strategy for aldehyde C–H activation.

Recent advances in metal catalyst- and oxidant-free electrochemical C-H bond functionalization of nitrogen-containing heterocycles

Frontiers in Chemistry, 2022
The C-H functionalization of nitrogen-containing heterocycles has emerged as a powerful strategy for the construction of carbon-carbon (C-C) and carbon-heteroatom (C-X) bonds.

C–H bond functionalization reactions enabled by photobiocatalytic cascades

Green Synthesis and Catalysis, 2021
Light may participate in biocatalytic processes either by direct light-induced biocatalysis or by cascading light-induced chemical reactions with biocatalytic ones, which are acknowledged as photocatalysis.
