Rhodium-Catalyzed C-H Bond Functionalization with Amides by Double C-H/C-N Bond Activation.

open access: yesOrganic Letters, 2016
The first C–H bond functionalization with amides as the coupling partners via selective activation of the amide N–C bond using rhodium­(I) catalysts under highly chemoselective conditions is reported.

Transition metal-catalyzed site- and regio-divergent C-H bond functionalization.

open access: yesChemical Society Reviews, 2017
Recent advances in transition metal-catalyzed C-H bond functionalization have profoundly impacted synthetic strategy. Since organic substrates typically contain several chemically distinct C-H bonds, controlling the regioselectivity of C-H bond ...

Steric, Electronic and Conformational Synergistic Effects in the Gold(I)-catalyzed α-C-H Bond Functionalization of Tertiary Amines.

Angewandte Chemie, 2022
Direct C-H bond functionalization is a useful strategy for the straightforward formation of C-C and C-Heteroatom bonds. In the present work, a unique approach for the challenging electrophilic Au-catalyzed α- C-H bond functionalization of tertiary amines
