Copper-catalyzed remote C–H arylation of polycyclic aromatic hydrocarbons (PAHs) [PDF]

Beilstein Journal of Organic Chemistry, 2020
The regioselective C–H arylation of substituted polycyclic aromatic hydrocarbons (PAHs) is a desired but challenging task. A copper-catalyzed C7–H arylation of 1-naphthamides has been developed by using aryliodonium salts as arylating reagents.

Transition Metal‐Driven Selectivity in Direct C−H Arylation of Imidazo[2,1‐b]Thiazole [PDF]

ChemistryOpen
A selective direct arylation of the different Csp2‐H bonds of imidazo[2,1‐b]thiazole with (hetero) aryl halides can be achieved simply by switching from a palladium catalyst system to the use of stoichiometric amounts of copper. The observed selectivity,

Direct C–H Arylation

CHIMIA, 2022
Bonds between hydrogen and carbon atoms are the most frequent type of bonds in organic molecules. The ability to replace hydrogen atoms by making other types of bonds to carbon atoms can enable simpler access to complex organic molecules by substituting
