Recent Advances on Synthetic Methodology Merging C–H Functionalization and C–C Cleavage
Molecules, 2020 The functionalization of C–H bonds has become a major thread of research in organic synthesis that can be assessed from different angles, for instance depending on the type of catalyst employed or the overall transformation that is carried out.

C-H activation of indole-derivatives catalysed by Pd-nanobiohybrids under mild conditions [PDF]
, 2022 A mild C-H activation of protected L-tryptophan catalyzed by palladium bionanohybrids was developed. Several Pd-biohybrids were synthesized and the influence of temperature or different enzymes as scaffolds were investigated.

Computational exploration of the reaction mechanism of the Cu+-catalysed synthesis of indoles from N-aryl enaminones [PDF]
Royal Society Open Science, 2016 We have studied the role of Cu+-phenantroline as a catalyst in the cyclization of N-aryl-enaminones using density-functional theory computations. The catalyst was found to bind the substrate upon deprotonation of its eneaminone, and to dramatically ...

Cobalt-catalyzed nucleophilic addition of the allylic C(sp3)–H bond of simple alkenes to ketones
Beilstein Journal of Organic Chemistry, 2018 We herein describe a cobalt/Xantphos-catalyzed regioselective addition of simple alkenes to acetophenone derivatives, affording branched homoallylic alcohols in high yields with perfect branch selectivities.
