Catalyst controlled remote CH activation of 8-aminoquinolines with NFSI for CN versus CF coupling
Catalysis Communications, 2021 A catalyst-controlled selective functionalization of 8-aminoquinolines with N-fluorobenzenesulfonimide (NFSI) has been developed. The use of GTP-Cu catalysts leads to CN coupling products and whereas the CF coupling reaction is dominant for GPT-Ni ...

Selectivity Control in the Palladium-catalyzed Cross-coupling of Alkyl Nucleophiles
CHIMIA, 2016 Site-selectivity remains a major challenge in metal-catalyzed C–H bond functionalization. Most existing strategies rely on the introduction of a directing group or on the intrinsic reactivity of the substrate.
