The Influence of Galactic Cosmic Rays on Ion-Neutral Hydrocarbon Chemistry in the Upper Atmospheres of Free-Floating Exoplanets [PDF]
, 1989 Cosmic rays may be linked to the formation of volatiles necessary for prebiotic chemistry. We explore the effect of cosmic rays in a hydrogen-dominated atmosphere, as a proof-of-concept that ion-neutral chemistry may be important for modelling hydrogen ...

Chemodivergent manganese-catalyzed C–H activation: modular synthesis of fluorogenic probes
Nature Communications, 2021 Bioorthogonal diversification of peptides is generally dependent on impractical prefunctionalization methods. Here, the authors develop a manganese(I)-catalyzed C–H fluorescent labeling with BODIPY probes, which enables the development of activatable ...

Electrocatalytic C–H Activation
ACS Catalysis, 2018 C–H activation has emerged as a transformative tool in molecular synthesis, but until recently oxidative C–H activations have largely involved the use of stoichiometric amounts of expensive and toxic metal oxidants, compromising the overall sustainable nature of C–H activation chemistry.

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.

Carboxylate-Assisted C(sp^3)–H Activation in Olefin Metathesis-Relevant Ruthenium Complexes [PDF]
, 2014 The mechanism of C–H activation at metathesis-relevant ruthenium(II) benzylidene complexes was studied both experimentally and computationally. Synthesis of a ruthenium dicarboxylate at a low temperature allowed for direct observation of the C–H ...
