Palladium-Catalyzed Ligand-Directed C−H Functionalization Reactions

Chemical Reviews, 2010
1.1 Introduction to Pd-catalyzed directed C–H functionalization The development of methods for the direct conversion of carbon–hydrogen bonds into carbon-oxygen, carbon-halogen, carbon-nitrogen, carbon-sulfur, and carbon-carbon bonds remains a critical ...

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

Nature Communications, 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.

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

Nature Communications, 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 ...

Visible light-induced direct α C–H functionalization of alcohols

Nature Communications, 2019
Alcohols are very useful building blocks in organic synthesis, however C–H functionaliztion in presence of free –OH groups is highly challenging. Here, the authors report a selective visible light-promoted α-functionalization of free alcohols with ...

Iron-catalyzed aliphatic C–H functionalization to construct carbon–carbon bonds [PDF]

Nature Communications
Although cytochrome P450 enzymes are powerful catalysts for hydrogen-atom abstraction from alkanes by iron-oxo species, the process typically leads to oxygenated products due to ultrafast oxygen rebound.
